Tom Mix...very nice, thank you. Have stared at that one for months, now it's clear as day

Also, thanks to the member for ID'ing the postal cover as from Austria. There was a composer autograph included in the collection, Franz Lehar, who is from Austria. The writing at the bottom left of the envelope almost looks very similar in style to his signature, with the curly loops, etc. I wonder if it just says something else, and this was the envelope the autograph and photo came in...I bet that's it.
