There is a photo of him here. There is a zoom button on the left. He is wearing gunner's wings. Looks like he has the EAME campaign ribbon with one star and the American Campaign ribbon. There may be a third solid color ribbon (left most ribbon). The fancy lapel pins show he was an Aide to a Brigadier General (one star on the shield). He was an aide to Gen. Edward M Morris , both in the US and later in North Africa. What is not there is an Air Medal (indicating combat flights).

The fancy pin on his right side (left side of the photo) is a Lafayette Escadrille pin. See here:

He claimed in an interview when he returned to the US because of his back injury that the French had given him the pin. He said that he and Elliott Roosevelt were the only two men to get it. He said he flew with the French out of Corsica. Since he was not apparently a pilot, he possibly could have flown as an observer/gunner. But did he?
