This is a set of 3 tintypes all taken in the same studio. Each is mounted to card stock and were photographed at the Mansfield’s City Gallery located in St. Louis, Missouri. The men are all Federal officers in descending rank starting with the captain. Sporting a pair of eye glasses, they are about stretched to their limit trying to accommodate his very wide head. Not sure how he was even able to see out of those as they don’t even line up with his eyes! He is followed by a 1st lieutenant and lastly by a 2nd lieutenant. I would assume these were all officers from the same company who went into the studio together. Very neat group.
