I sent a letter, SASE and a photo on Oct 15 to
Grease
c/o Brooks Atkinson Theatre
256 W. 47th St.
New York, NY 10036
USA
He kept the photo and sent his own instead. So far, so good. The photo is gorgeous! Even better than mine, I would say BUT it was too big for my envelope. So he bent it PLUS the signature is smudgy (this isn't his fault...).
It's only a few more days that he's part of the Grease company. If I had gotten this success sooner I would have tried another shot (with a larger envelope!) but the letter wouldn't make it till Jan 4 due to New Year's Eve etc.... Well... MAYBE I will send only a letter and SASE today but I'm not sure yet.
At least 2 of my stamps haven't been cancelled
Awesome success!
