I know it well -- it's genuine, from Apollo-16 just after TEI. Crew is photographing receding moon. Image appears to be window reflection of sunlit camera lens assembly. I asked all three crewmen about the image, none recalled noticing anything unusual -- and there's nothing on the Hasselblad desequence or any other camera, as there would have been if something s-t-r-a-n-g-e had been seen.
