Japanese Bon Bon Felt Tina hat in EUC

Handmade, 100% wool, unusual hat. Greens, purple-greys, yellow and tan felt discs pinned on. I believe it fits a size M/L, though I have a small head and it was fine on me. Purchased from the Peabody Essex Museum during their Japanese fashion exhibition in the 2000s. From a healthy, non-smoking, no pet household. Recently gently hand-washed, air-dried.
