You're a fountain of knowledge and enlightment pal! Thanks for making this brilliant picture make more sense!
No problem.
I think this might be the pair being billed as the Aztec Children in the early 1900's. Of course they weren't Aztecs, but maybe they slapped that on the tunic as an Aztec-looking symbol.
This is also true. Here's a pic of them as adults. " Stephen Brenner with Two Aztec Children"
*EDIT* This is NOT a picture of Schlitzie. I made a mistake and this is a pic of another couple of old "Aztec Children".
