We all know that with baseball cards and comic books, the “oops” editions tend to be the major collector’s items. Got that discontinued ’02 Bonds Topps card where he’s seen swinging a giant syringe? Hold onto it!

But yeah, the same theory holds true for cameras as well, as this Leica M4-2 Safari Prototype proves. This mint-condition beauty is one of a precious few examples of the camera that was supposed to join the R3 Safari 35mm camera on the market in 1977. But it never happened as planned by E. Leitz Wetzlar (founder of Leica), and that’s partly what makes this prototype so valuable. This highly coveted piece of history just went up for auction at Stan Tamarkin before going for a winning bid of $22,000.
