Harry Hudson Rodmell
After serving with the Royal Observer Corps during World War II, his graphic design work was largely replaced by commissioned oil paintings of new vessels. These were often produced from plans so that a painting could be completed before the vessel was launched.
Aircraft recognition
Recognition competitions were organised locally, regionally and nationally and by the start of World War II the Corps had trained nearly 30,000 volunteers to accurately recognise all types of current aircraft. The unofficial "Aeroplane Spotter" magazine was later renamed as "The Journal of the Royal Observer Corps Club" before being adopted as an official publication and renamed as "The Royal Observer Corps Journal" published by HMSO and distributed to every observer at a price of one shilling (5 new pence).
