Extremely Rare Sideshow Freak Photo Skeleton Man Circus OOAK Eisenmann Test signed signature is hard to readOriginal CDV of a thin skeleton man.. a well known Victorian Era sideshow performer. Possibly an extremely rare, even one of a kind photo I picked up a decent sized collection of these sideshow people images and quite a few were on this pink mount with blank backs. a note that was with the collection said that many were TEST SHOTS for the famous photographer Eisenmann. I was not able to find another example of this same photo online. CDV is 4" x 2. 5"
