Pre-WWII US March Field Army Air Corps Officer Visor Cap. Cap is a size 7 3/8. The cap most likely belonged to an Army Air Corps officer at March Air Field, with the Ordance Day program being found folded and tucked within the cap. The cap is in near-mint condition with little to no damage to the interior or exterior. All leather is soft and wearable. Excellent cap badge as well. An overall nice and interesting piece.
