A very long time since I posted, but hello especially to AVP, my old advisory council buddy!
Yes, the poster was sold, initially only to attendees of the VIP party, which is where the photo with Mikey E and George was taken. As I understood it, they had the artist, Drew Struzan (who did many of the LucasFilm posters during original release, including the most recent one) sign a number of them, and had intended for Lucas and Eisner to sign more. They may or may not have done so - I wasnt at that party! But I did see one on display at the Gallery (oh how I miss thee) and asked. A very kind a patient castmember from merchandise (admin, not front end) named Becky put up with my incessant inquiries and lets just say that after making myself a pain, I and a few others were able to purchase some left from the VIP event when they were released. It is now framed and in my stairwell with my other 2D DL treasures (signed by Drew). I cannot say for sure if they ever sold them in a non numbered, non limited edition format.
The LE print shows up occasionally on Ebay; Becky left DL years ago. The Gallery, with the 2 Beverly's and Michelle, and all of the wonderful events pre internet, are beautiful memories. I thank all of you who made those times possible.
