Hi guys, this is Kevin from Twitter with the Part III print. Let me know what I can do to help.
I'm a pretty big fan thats been active in the BTTF fan community for years (organizing events, etc), and I am the only person I know that owns a BTTF print. I'm afraid that all BTTF and Part II prints in circulation (like the one screening at the Alamo DF) might be owned by Universal.
