Them being a throuple may be true. I found a random Twitter account claiming that this is a Dr. Federico Oloriz Aguilera and his two "traveling companions." It provides a clothed picture of them as well. He was Spanish and lived around the late 1800s. I can't find any details.View attachment 150032481
They’re pretty likely to be quite long dead. And no, this in not from my collection of any family photos with a context I’d be able to discern.
But my fantasy guess is a resounding no to them being brothers. Sharing a type of mustache does not make you related.
I sincerely hope they were a happy horny throuple. And by their faces, that’s what believe they were.
