Royal Mail’s first stamp issue of 2011 celebrated the pioneering work of Gerry Anderson, best known for 1960s children TV series such as Joe 90, Captain Scarlet, Stingray and Thunderbirds, all made using specially designed marionettes. The set of stamps also included Royal Mail’s first ‘motion stamps’ on a miniature sheet using micro lenticular printing. Several seconds of the original Thunderbirds footage, which plays at 30 frames per second, were re-edited to 36 key frames for the project.
