Old Tintypes and Photos

I found these photos at the Pomona Antique Fair in May. The top two are studio type photos, and the bottom two are tintypes.

Thomas is the name I have given the man in the tintype on the bottom right. I am currently working on an original piece with his tintype, and have created a short narrative for him as well.

The two women in the tintype on the bottom left look so prim and proper don't they? And the young woman in the upper right is lovely.
