I doubt if there's much I need to say about these, except maybe "I told you so", if you read the last post. Oh, and there's a guy typing a letter which you can make out on the left side of the photo.
Shoot. Well, I should also add that he's wearing what are called breeches, which were a carry over from cavalry riding pants, apparently. I was confused about this, thinking they were called "putees". Turns out those were worn by infantry to keep the mud out of their boots. I'll leave it at that. There is a ton which could be written about his uniform and hats, and of course the artillery shell.
So, another bit of a milestone has been reached! We've finished the first scrapbook containing aviation photos! I'll count to make sure, but I think there are three more with aviation photos. Ivan donated some photos to the Marine Corps Museum at Quantico, I believe, so we obviously won't be seeing those. Oh, there is also an addition to the collection which I recently received from my sister. A beautiful artillery shell which has the top lip decoratively curled, and is embossed with "1918" diagonally across the shell. I'll post a photo of that, eventually.
