Rare Antique Photo Tintype Gay Interest Men Holding Hands + Union Case

Remarkable tintype showing two men holding hands + Union Case. I took the tintype out of the case to see if I could find the individuals' names written somewhere, but did not secure any info as to the identity of the two lads. Condition as shown. The case is chipped at the clasp and has a split corner, but is otherwise in good condition. The patriotic metal vignette reads "Constitution and Union" along its inner edge. Tintype is missing some emulsion near top and lower edges (probably the result of friction with the metal vignette.). Tintype is 2 1/2 by 3 1/8 inches. Case is 3 3/4 by 3 1/4 inches and 3/4 of an inch tall. I did not reinsert the tintype inside the case to prevent further loss of emulsion.
