I bought these at an estate sale because I thought they were unusual.  After much research I think these are a wrestlers promo photos or an art project. 

I'm not sure who the subject is, or the purpose.  I believe they are from the early 1900's.

This is the last of the batch. 3 are photos, the 4 at the top look like they were intended to be post card. Maybe for promotional purposes.  Just a guess.

If you know more, please feel free to share your knowledge.
