I never put much thought into the frames before as all my posters are oversized and cost a fortune , but reading this I may double think which way I go the next time.. I cannot use glass as its too heavy and has a high probability of cracking in a 5 foot frame so acrylic is the way I go .. My framer literally wrote the book on shadow boxes and framing.. He teaches in Europe , and writes articles all the time in some framers magazine.. Helluva skill set .
Sounds good, Mike. And with your larger sizes that require more custom framing, it's the way to go. And you are smart and wise to not use glass. it is death to posters as it retains heat and moisture - much more so than plexi, and is simply not good for paper. Any number of fellow collectors and dealers here have also expressed this same sentiment. And with you living in a more humid part of the country (during the summer months, at least), the last thing you want is foxing or other damage to appear on your collection.
Your frames look outstanding, there is no question about it. Your framer and you have picked materials and colors that compliment your posters to a T!
