Years back there was a b/w silent print that someone had for sale near Cuckyoga Fall, Ohio, but I was too late in getting over there. Someone else got the print literally five minutes after arriving. After this new discovery, I'm thinking it wasn't b/w at all, but rather one of the lost 4d elements as a raised negative or positive reversal. Wow! Someone out there has it, and it's probably on the shelf next to the lost color Barney Google prints.....
