This weekend, the iconic British sci-fi programme Doctor Who turns 50. We're all excited for to see how the anniversary is marked - especially given that the Third Doctor, Jon Pertwee, was one of our celebrity supporters.
Jon Pertwee signs our commemorative First Day cover with blind veterans Phil Duffe and Ray Hazan
Jon, who took up the sonic screwdriver in 1970, lent his support for Blind Veterans UK's 80th anniversary. The charity, known then as St Dunstan's, commissioned a First Day Cover for a set of commemorative stamps, with funds going to the charity. Jon was one of a number of public figures - including The Duke of Westminster, General Sir Peter de la Billiere, climber Rebecca Stephens and fellow actor Anthony Hopkins - to sign the cover.
The cover was designed by blind veteran Phil Duffee, and featured a logo showing fellow Blind Veterans UK member Reggie Perrin's attempt to climb Mount McKinley in Alaska.
