I bought this both new and framed and not prohibitively expensive.
Obviously a custom job, but interesting.
1 sheet framed with glass on both sides, ideal for hanging in the middle of a sports bar with high ceilings or in a home with a great room with cathedral ceilings, which I have. Unfortunately my wife wont let me hang it in the living/dining/kitchen=great room and it resides in a stairwell where virtually no one sees it, not even the sun. I flip it over every few years to look at the other side. I realize 1989 Upper Deck Baseball is not vintage, but it is the first product they ever produced, a real chunk of baseball card history that even includes the RaJo rookie card. With color images on both sides this issue may be the first to lend itself to this type of display. Photos in the second, fourth, sixth, eighth and tenth rows were actually taken with the camera held upside down.
Glass on both sides ...... something to think about, at least for a moment.
