I found a group of six of these old templates this week in Maine—where gloves and mittens are certainly a necessity for a good chunk of the year!—and find them so beautiful. These two were obviously for cutting mittens—these two just slightly different in size, one with an old sticker noting it as a size 9 1/2, so I believe the other is a 10. Nice weight smooth board, which has acquired quite a good patina, with wire edging that shows a little rust, all to the good. I especially love the shapes of the wire-trimmed cutouts for the finger holes, making them look rather like painters palettes. Super graphic and to my eye both gorgeous and quite evocative.
Left in first photo: 10 3/4 x 5 3/4. Template with sticker: 10 7/16 x 5 5/16. Very good condition, sturdy and sound, early 20th c. I would guess. Price is for the pair.
