The Royal Mail is to release a set of stamps to celebrate the 50th anniversary of Doctor Who next year, with the first day cover reportedly due on 8th January 2013.
No other details are available at present, with the Royal Mail informing us:
It won’t be the first time that Doctor Who has been officially recognised in such a prestigious way. A Dalek was chosen by Royal Mail to represent television in The Entertainers’ Tale issue that was released on 1st June 1999. The set also comprised Bobby Moore (sport), Charlie Chaplin (cinema), and Freddie Mercury (popular music).
