I thought people would be interested to know that the color hopper photos that Bob's is selling are from a group of Kodachromes owned by Randy Anderson. He found them in a hobby shop in Florida, whose owner said he thought he would never find someone to buy them. Apparentely he had had them for a while.
Bob will often print peoples negatives and slides for resale, with agreement worked out with the owners about compensation.
Randy and I have both wondered what else the photograher may have taken and have half jokingly talked about hiring a private detective to try to find who the person was and if there was any more material.
