Very few of us have full-size set pieces, but I think several of us have decorated our basements in Early American Game Show. Whether it's displaying a home game collection, or putting up 8x10s you've collected off Ebay, or creating items yourself from scratch, or any number of other creative approaches, if you're a fan and you have the freedom and imagination, there's really no limit.
I no longer have a basement, but I have some fun and relatively rare items that decorate my walls. I have three poster-sized professional prints of TVG covers, two for I've Got a Secret, and a third for Bill's one solo cover. I also have what might be a unique set of caricatures of the 70s To Tell the Truth panel, which were drawn for an event honoring Kitty Carlisle. I also had three full-page ads from Variety Magazine featuring Bill, but I've since turned those over to Adam.
