I've seen (and bought and sold) one other mold like this one several years ago--that one came from the collection of the Marilynn and Sheila Brass, better known as the "Brass sisters," originally of Winthrop, MA, who authored cookbooks, hosted a cooking/baking show on PBS, etc. etc. I'm not especially devoted to pewter ice cream molds in general, but I'll snap up one like this whenever I come across it: a wonderful sculptural form, composed of three fat links on each side, evoking the FLT Odd Fellows links, standing for bonds that never break, also also also evincing the twists of a pretzel. Stands up on its own if slightly opened, which is how I would display it.
5 3/4" x 2 3/4" x 1". Very good condition, nice patina to the exterior, early 20th c. I believe.
