How do I post message with autograph

[Lee41]

Hi there, I sent Alex Trebek the TV game show host of Jeopardy! a get well card on May 27, 2019 and I received an autographed photo from Alex on July 4, 2019. I'm trying to figure out how to post my message with the autograph ed photo that I received in the mail and I can't seem to find out how and where do I post mine! Today (July 22, 2019) happens to be Alex Trebek's 79th birthday and I would like to post mine on his birthday if possible. Can anyone please tell me how and where to post my autographed photo with the date I sent out my card and when I received the autographed photo, a long with the Jeopardy! address? Thanks!
