I think the "but one was real" claim sounds like a recent bit of revisionism to me. Living in the northwest "granada" area and being just about old enough to remember interviews with the sisters being covered by regional tvs own Bob Smithee, the way I recall it was that till the bitter end they claimed the pics were real and not fake. Until one died and the other now very elderly sister came clean to our Bob that they had indeed faked them. The caveat was "but we really did see fairies, we just knew no one would believe us". It was decidely not "but one of the pictures is real". This forum is the first time I've heard it.
