SPACE 1999 AUTOGRAPHS

Well, I seem to have caught the 'Space 1999 autograph bug' after having obtained the autographs of Prentis and Catherine at last months Birmingham NEC Memorabilia Show.
So far, over the past week, I have located on ebay and purchased 'authentic' signed photographs of Martin Landau, Barbara Bain and Ziena Merton.

Next up, will be searching for signed photographs by Nick Tate, Barry Morse and Tony Anholt, although I expect ones by Barry and Tony would be quite expensive as they are both sadly no longer with us.

Then it will be onto the other non-major actors / actresses.

Anyone know the best way of tracking down publicist addresses or contact details for actor / actresses ?
And anyone else out there who has managed to collect loads of Space 1999 autographs ?
(PS I know Kinggodzillak on the Eagle Transporter forum has managed to collect a very impressive collection so far)

I recently sent Martin Landau a letter and a colour photo of himself asking if he would kindly sign it and return to me. Also did the same for Nick Tate (with a photo of Nick). I even included the money for the postage !

I am hoping for a result - will let you know the outcome. Has anyone else tried this route and been successful ?
