Mounting and framin an autographed sports poster while preserving its value

Factual Questions
1

I have an autographed basketball poster I would like to get mounted and/or framed as a gift.

It’s probably not worth much, but even so, I don’t want to do anything to destroy its potential value as a collectible. Any advice? Would dry mounting ruin the poster’s value? Is there a better option?

A good framing shop can mount and mat your poster using simple archival corners. These will adhere to the backing board without adhering to the poster itself.

Dry mounting is permanent, and will surely detract any value from the item, save for sentimental.
