Hi all - new member here - I have an interesting item I'd like some help with. I appreciate this is an old thread (last post June 2020) but perhaps Exile on Main Street is still around? Or Marvel Team-Up #18? I've attached a photo of my item. It's a hand colored Supersnipe gallery Star Wars exhibition poster. The story I have is that this was hand-colored to be displayed at the Supersnipe store or gallery. The original purchaser bought this directly from the store back in the day, along with a regular Star Wars exhibition poster. A few years ago he sold them both - I picked this up from that buyer, so in theory I'm the third owner. If anyone has any more information I would love to hear it. I haven't seen another copy of this poster colored in this way, or with this back story, so I'd love to chase down more of the history if I can. Thanks!
