Some notes first: if you are interested in learning a little about Cinecon, here's the website - http://www.cinecon.org/
Eddie Brandt's is a video store in North Hollywood, California that carries a ton of movies for sale or for rent. There's a $15 lifetime membership fee, but they get a lot of donations by people who have recorded movies otherwise unavailable, so the membership may be worth it if you like searching out the old, rare films. They also have paper items for sale such as lobby cards and posters. If you go there, check out the walls. And also thank you so much to the person who told me about this store!
This is my original lobby card! The first one I've ever purchased. I thought this photo was adorable, and I couldn't resist.
