What's the best way to frame valuable sports posters? I called a frame shop and he said it was routine for them to "mount" the poster on a backing board!
When I told him I wanted to preserve the "original state" of the poster, he said another method is to use clear corner holders to keep the poster in place. These wouldn't actually be attached to the poster, but may be visible when looking at the frame.
Does anyone have any experience framing odd-sized posters of a sports nature?
I've also heard that even the best frames have to be re-inspected after several years go by to check for moisture, etc.
Thanks.
