I wanted to share more of these tintype photos of Mr. Debonair so you can judge for yourself whether it is the same man. The first image is a one-fourth plate tintype which is larger than the usual one-sixth plate tintypes. In these first two photos he is on the left and wearing his top hat.
In this third photo he is wearing a type of bowler hat and posing with three three children I can only assume are his own children. Note the picture on the bottom left he has no mustache, the one on the right he does.
And then finally I have a couple of pictures of him as a younger man, first posing in a nice suit as usual and wearing a white bowler. In the last photo he is even younger, is once again wearing a suit and for the first time is not wearing a hat. He is posing with another young man - perhaps a friend or a classmate.
I'm quite fascinated with Mr. Debonair, unfortunately I'm afraid the mystery of his identity will never be solved.
