The only date is 1921. Left "All dressed up". Right: "Vamp". I don't know who that was, but she was stylin'. Left picture is badly faded but Photoshop really brought it back.

Left: May 22, 1921. "Our Ford Sedan". "Don't you like it". Right: May 23, 1921, "Back from a N. H. trip. Bushnell Park Hartford Conn." This picture is a puzzler for me. I think Margaret is on the right- her lower face is distinctive. That could well be Marie on the left. A girlfriend in the middle? But the older folks just don't look like the other (rare) pictures of Niels and Albertine. Given the date it must be after a road trip in their new car, so it would have to be them. Any ideas?

Left: May 21, 1921. "Ed Clarke". Right: May 22, 1921, "Leon". No clue who these guys are. I just included the pictures because I think they are really neat..

June 1921. Left: "Part of my S. S. Class". Right: "Elizabeth Park June 1921" "Chums". I think that's Margaret on the right.
