1852, ½a red Scinde Dawk tied by small diamond of dots to fragment. This is the first stamp of Asia and a great rarity. In order to prevent from it being reused, this stamp was made out of wax so that it cracks upon usage. As such, out of the handful of examples that exist, most are found heavily cracked and mounted to a different piece to which they do not belong. This example is in an excellent state of preservation with minor cracks, on the original piece of the letter to which it belonged. A great rarity. APS certificate.

BPA certificate.

1854, 4 anna blue & red 2nd printing Head II Frame I with major error "Frame Double" (SG 19var) cut to shape with traces of margin in places, cancelled with diamond of dots with part cds in red on top.

1854, 4 anna blue & red 4th printing (SG 23) unused horizontal pair (position 14-15) with margins all around, minor spots at upper left not detracting from the beauty of this appealing unused multiple - multiples of unused 1854 4 annas are extremely rare. BPA certificate.
1854, 4 anna red and blue 5th printing Head III Frame II (SG 25) position 7 unused with unusually large margins all around with a prominent retouch of the Queen's profile and nose (previously unrecorded). A superb copy with rich colours. Sismondo certificate.
1854, 4 anna blue & red Head III Frame II with pin perf all around (SG 30) neatly cancelled by Arcot "C/124" in diamond of dots. A great rarity of which only three eamples have been recorded - this being the finest known copy; illustrated on plate 7 of the Martin & Smythies book. BPA certificate.

Whether it's an educational site, app or a physical product, you can help kids engage with your work by following some simple rules.
When it comes to designing for kids, there's one thing for sure – kids aren't just miniature adults. Rather, they present a completely different set of interaction, experience and usability conundrums.
To get a handle on how to design better digital products for kids we spoke to education professionals exhibiting at Bett 2015 – the world's leading event for learning technology.
Why is design so important for learning?
"Designing for kids is one of the most demanding fields there is," says Gary Beckett, Education Consultant at open source specialists, Precedence Technologies. "Kids are fantastic critics; the amount of technology at home and within education means that the look and feel of an object is almost as important as the job it performs."
Ben Dunford, Director, ePraise, a leading parent-teacher communication platform said: "Keep things simple – students don't like clutter and are easily distracted. Don't add irrelevant things to the screen, and lay things out in a sensible way with plenty of space" suggests Ben.
"It's also important to remember that kids grow up very quickly – something designed for a 15 year old may need to look and work differently to something designed for a 10 year old. Be as specific as possible about your intended audience, in order to get the best outcomes."
Filippo Yacob, CEO, connected toy specialist Primo, agrees that simplicity is vital. He advises: "Children are kings at cutting through all the fudge; stick to a simple story, it's more honest. I'd also say that it's important to make it 'un-master-able' – the best toys and games are easy to learn and impossible to master, giving you the opportunity to re-define your own long term goals and overall narrative."
According to Ingrid Connors, Founder and Director of mobile app, variety and surprise are key to keeping children engaged. "At Monster Phonics we found the key is to create a dynamic world. Children love surprises. They want to see something funny or unusual.
"It's important to connect with a child's experiences in the real world too," explains Connors. "Children respond best when they can clearly see that they are making progress. Small rewards along the way are vital. The reward system should allow the children to make choices, customising their online world."
Paul Croft, Director of UltimakerGB and Founder of CREATE Education Project believes in participation from the children to keep them invested.
He explains: "With the maker movement sweeping the globe and brands like Nike allowing you to personalise products, it's not just kids who are getting excited about the transition from being consumers to prosumers!"
"Never before have we had the opportunity to get involved with designing our own products as we do now. Children love to be involved in creating and putting their unique stamp on something. What better way to keep kids invested than to give them true 'ownership' and a community to share with?"
Paul Howell, founder at Stop Motion Pro, specialist in animated films, believes video demonstration is another great way to get children to engage with digital products.
He comments: "Supporting your product by creating student centric video demonstrations is a great way to engage kids in schools. Showing actual students solving creative challenges is a great way to help other kids see how your products will be relevant to them and their projects. They very quickly apply the ideas from the instructional videos to their own work, then everyone wins."
Zulfi Baig, Operations Director, iBoardTouch, provider of interactive touchscreens stresses the importance of the device itself, not just the design.
"Enhancing learning and engagement in the digital classroom can be achieved with investment in the right piece of tech, used in the right way," says Baig. "Devices must offer diversity in collaboration and interaction connecting students and teacher, student and student; and student and interactive board with any type of BYOD device."
It is important that children continue to be engaged in digital products outside of the classroom, to ensure that the learning process continues. Simon Davenport, Senior Direct Marketing Manager, LEGO Education Europe concludes by explaining why this is so important: "Encourage continued learning outside of the classroom – this is where the power of digital learning really comes into play.
"By establishing a two-way interaction with parents, children can take their classroom experiences into the home and work with parents to keep the learning journey alive."
Bett 2015 is free to attend and takes place from Wednesday 21 to Saturday 24 January 2015 at ExCeL London. You can also follow the conversation on Twitter.
