Secretarial, sorry. There should be an "r", not "Chall".
Agree, definitely secretarial, these used to be sent out in reply to TTM requests
Thanks guys :)
Funnily, I suppose the picture to be secretarial signed, but I do believe the sig on the note to be authentic. As far as I know Heston himself at least indicated every single letter in his name, which in my eyes is the case with the sig on the note, but not on the pic. Especially the "r" in Charlton and the "s" in Heston should be kind of visible in authentic form.
That's interesting KaiMi - I assumed that signature was printed!
It could a printed autograph of his actual one, depends if you can tell if it's live ink or truly just printed on.
