Same here, although I have recently thought of replacing mine (which hangs, stereotypical, directly behind my desk) with a very large oil painting of my dog.
Sitting in a storage building in MO (with everything else I own)...I am currently in WA...hopefully will get them hung in a few months when we do what will hopefully be our final move for a LONG time
I only have the one from the Defense Language Institute, but it is in a binder with all my promotion warrants and awards and etc.
They wouldn't mail it to you? Ironically, the only diploma I've ever displayed (as in framed and mounted on a wall) is my diploma from the Boston Police Mounted Academy....the most difficult and miserable 8 weeks of my post-military life.
I could have picked it up for free when I'd just graduated but was very busy getting ready to move to San Diego. They would have sent it to me for a small fee but I didn't have any use for it anyway, so I never bothered.
My AA is mounted in a really sweat antique oak diploma frame with green matting that my wife picked up at thrift store for around two bucks. My BS is located in a desk drawer underneath a bunch of stuff until my wife scores another antique frame.
