Pink, red and blue cotton print fabric was used to make this antique style bonnet at some time. I would guess 1940s or later, the fabric seems 40s. Soft back that buttons onto the stiff brim. The brim has sewn sections with pieces of cardboard in it. The cardboard pieces can be removed. Elastic on the back of the neck with gathered fabric below it. Long ties.
CONDITION: The bonnet is in excellent condition. Fabric is nice and bright as if the hat were never used. Some of the buttons holes might need to be tightened up to keep them from opening.
