Happy Birthday, Ian Marter (Fourth Doctor Companion ‘Harry Sullivan’)
“From the first (I think) ChicagoTARDIS con, although it had a different name.”
Back row: Ian Marter, Tom Baker, John Nathan Turner, Patrick Troughton (and beard), Peter Davison, Jon Pertwee and two people whom I cannot identify, but who are probably members of the crew. Front row: Janet Fielding, Elisabeth Sladen, Carole Ann Ford, Mark Strickson, Sarah Sutton, Louise Jameson, Mary Tamm and Nicola Bryant.

Doesn’t Ian look jolly? hehe. This picture is pretty epic though, considering everyone who is in it.
