I'm curious when the autographs were collected. It must have been during more than one taping session because traditionally, Betty White, Marcia Wallace, and Fannie Flagg wouldn't have been on the panel at the same time. Maybe the game belonged to someone in the audience who brought it more than once.
Depending on how you feel about the veracity of this site, it would have had to have been at least three taping sessions (or the original owner got some of the signatures separately). Betty and Fannie both did tapings in August 1975, but Marcia didn't have any bookings on
MG between March and December of that year.
https://markgoodson.fandom.com/wiki/Match_Game/Episode_GuideJust a warning that in the sports memorabilia business, a fair number of the signed items are not legitimate -- to the point where until you have a certificate of authenticity, a lot of resellers won't have anything to do with them. (That's how I got a "signed" Magic Johnson card from a disgusted coworker; I also have a nearly-one-of-a-kind Shaquille O'Neal signed press sheet that I probably can't resell for what it's actually worth.)
Matt O.: when was the second edition of the
Match Game '7X home game released?
