I've recently moved house, and in the move managed to persuade the missus to let me have a man cave (AKA the smallest of the three bedrooms). In the 30th anniversary celebrations in Newcastle back in 2013 I went to the Tyneside Cinema showing of Private Lives ("Howay kettle") and bought a 30th anniversary poster which I got signed by Dick Clement, Ian la Frenais, Roger Bamford, and Melanie Hill.
I didn't attend the evening do at the Hilton (and I've regretted it every day since)
Anyway I'll get to the point, I have set myself a potentially impossible task - to get that same poster signed by the five surviving main cast members as well as any one else involved in series 1 and/or 2 that I can.
The problem is, I don't know where to start, and I'm a bit worried that I might be lucky enough to get a few signatures and then send the poster off for another signature and it either get lost/damaged in the post, or simply not returned.
Has anyone else attempted anything like this, or does anyone have any advice for me?

Thanks gang
