Hammon wrote to Bernice McGee on Dec. 16,1971.
In the letter he told her that she could view the stones "without tape" upon payment of the fee proscribed by the board of the Flagg
As far as I know, the b/w photos of the stones on black cloth were taken in 1965.
While I can only say I suspect
they were being held by the FBI in their Phoenix office at that same time, and that these were "evidence" photos, I'm certain there is at least one other person who knows for sure.
Richard Robinson used the same photos, but with lower resolution, in this article about his and Reyes solution.....http://www.lost-dutchman.com/dutchman/t ... eGate1.htm
I may be misinterpreting Hammons' statement in Dean's article that he taped the copies, since he does not mention "copies" in the article, but there are reasons I suspect there were two sets of stones in the AMMM by that time. One being the "without tape" offer.....meaning repeated application and removal of tape from the "original" stones ? Another being the "two hour" limit, suggesting the "originals" without tape were only to be viewed by patrons, not the public who would be present during open hours at the museum.
