Antique Early 1900s Leather Motorcycle or Aviator Pilot's Leather Skull Cap

Antique Early 1900s Leather Motorcycle or Aviator Pilot's Leather Skull Cap

These were found with a pair of Hansen's leather motorcycle riding glove, so I presume this is a motorcycle skull cap from the early teens to twenties.

Hat is in fair shape. Leather strap is broken and brittle. There is a tear in the leather near the top.
