True story...for my very first photo show I "framed" the dry mounted prints under window glass, with an inch of duct tape simulating a frame, the rest of the tape wrapped around the back. Stuck to the wall with mirror-mounting tape. When you've got $62 to do an entire show, that's what happens. I bet framah is taking notes.
Flash forward 47 years, they're in a cardboard box in my garage, duct tape, fractured glass, and all. The duct tape still looks good, which must mean it's archival. Will bring in million$ at a Sotheby's auction when I'm dead.
