Looks way off to me, but some celebrities changed up their signatures over the years. I'm interested in your opinions. Added a poll, too. Hope I did it correctly. Thanks!
That's probably fountain pen on there, but who signed it is anyone's guess. It could have been Mr Burr, it could have been a secretary (they did it all the time) and it could be someone who just liked Raymond Burr.
I can't imagine a Raymond Burr autograph would be worth forging. However...many actors have their staff sign photos to send out.
Most likely done by someone at his talent agency. An (found) autograph is much more likely to be genuine than an inscribed photograph. Debora
