text: Sometimes, putting up a billboard just isn't quite enough - so a group of Russian entrepreneurs have come up with a new way to get you message out: on the breasts of a beautiful woman. Companies Tittygram and Titisign have popped up in Russia offering the eyebrow raising service and are, by all accounts, causing quite a stir. Indeed, it has already caught the attention of one big company, which jumped at the chance to advertise its whoppers. Cleavage: Burger King has become one of the first big companies to take advantage of thi type of advertising . From the heart of Russia: Two companies now offer to write on a woman's cleavage and take a snap . Burger King's Russian branch posted a picture of a woman with 'I love Burger King' emblazoned across her chest, courtesy of Tittygram, on its VK page, the country's version of Facebook. The message above reads: 'Do you want your name to be written here? 'Every week the most active participant will get such a named postcard from us! 'Not only our whoppers are prepared on fire, everything we have is on fire as well!' And it has certainly brought them a fair amount of attention, with hundreds of 'likes' and countless comments - although they are not all positive. What's more, as advertising campaigns go, it is incredibly cheap: for as little as $6, or £4, they promise to get your message across in a way which is certain to grab attention. Versatile: The picture can then be used as either a personal message, or advertising, and cost just £4 . Eyebrow raising: But the use of a woman's cleavage as advertising space has not been universally popular . According to the Global Post, Tittygram was set up earlier this year, with Titisign following in its footsteps more recently. Both offer a similar service, asking people to send their messages in, at which point a model writes the message on her breasts and then takes the requisite photo. The English website for Titisign boasts: 'Stave off boredom! Send your communication on the bosom of Russian beauties – knock your friends’ socks off, advertise your business and make unforgettable gifts! 'Say hello from the heart of Russia!' Boasts: 'Knock your friends’ socks off, advertise your business and make unforgettable gifts,' says Titisign . Alexey Gavrilov, co-founder of Titisign, revealed to MailOnline the company gets a range of requests for messages - from 'Farewell, Semyonych. With best wishes for your wedding day' to 'Do not play with heart - it is one. Play with boobs - there are two of them'. The women, he reveals, are not all professional models. 'We invite not only professional models who are interested in our project and like our idea, but beautiful girls,' he explained. 'Some of our models we find in professional community - we have photographers in our team - and some of them we find through social networks, others find us themselves.' However, as one VK user points out, when advertising 'it is necessary find something that is interesting to everyone' - and this certainly is not.
