This is a puzzler--for such a VIP affair there is little to help ID the scene. The 20's seems right. I don't think either of the suits is FDR--he was younger when assistant sect. Not Truman. I feel like neither suit is a president. The one on the left could be Wilson if he was a stress eater and had his jowls removed. Could be a ship-launching--there were and are shipyards on the Great Lakes.
