Vintage 1930s CROWN Classic Tweed Men's Cap

RARE Vintage 1930s CROWN Herringbone tweed cap with fold down flaps and chamois lining for warmth. The brim is secured with a functioning metal snap Condition: Aside from one stain spot on crown, it's in very good vintage condition. Sizing: 21" to 21.5"? I'm a 22" circumference head size and it fit me very snugly with flaps down but it was definitely too tight with flaps folded in, so I suggest smaller than 22" for ideal fit
