Everyday Fellows of the Golden Era?

From Shorpy, the Hollywood High School "Traffic Squad" in 1933.

Some more of my grandfather, Bill Conwill. The upper right photo was taken at the Kansas City train station in January, 1938. The others are all dated 1940. In the images where he's playing tennis, I believe he's wearing a jacket similar to the one attached. I wish I could read his t-shirt!
