I'm using a deck of brown Wynns to get magician autographs. I only just started at the Blackpool convention, so I haven't got many yet, so far:
Shoot Ogawa
Kostya Kimlat
Lennart Green
Pete Firman (a quite well known TV magician here in the UK)
Geoffery Durham
Ali Bongo
and, my favourite so far
Roy Walton, who just happened to be sitting in the row in front of me in the gala show at Blackpool.
And today, I got Derren Brown's autograph for my girlfriend.
