Pretty simple as far as handmade masks go, but quite evocative things I think, and though all more or less the same, to me at least each has its own particular temperament! One finds some similar that were made in Japan, but several others I found these along with are stamped Germany on the reverse, so I believe they are too, and I would guess date to the 1920s-40s or so.
Smallish face sized: 5 15/16" t x 4 7/8" wide, measured straight across the back (not on the curve; 2 1/4" d. Very good condition. The one at lower left (in first photo) shows some black staining or soiling on the left side. One would need to attach ribbons or elastic at the temples to wear, or thread a little loop or two to hang.
Price is PER MASK. If you have a preference as to which you'd like, please indicate in the notes field at check-out by noting its position in first photo.
