who are those two? I’ve seen them before-
Unfortunately, Bob, those were two real brothers.
I read someplace before that they were a part of the Mengele experiments with twins.
They are Dresie and Casie, Twins, Western Transvaal, photographed by Roger Ballen in 1993. There is internet speculation that they have particularly severe Fragile X syndrome.
