Vintage Duncan DM-421A Seal Family Ceramic Casting Mold — In Original Box, Fresno Calif.

One pour, and a whole seal family comes to life. This vintage Duncan DM-421A "Seal Family" casting mold produces two seal fronts, two seal backs, and one baby seal per casting — two seals and their pup from a single mold, ready to assemble, paint, and show off.

Best of all, it arrives in its original Duncan box, label and all — right down to the hand-stamped $3.98 price circle from the days when Duncan Ceramics of Fresno, California billed ceramics as "the world's most fascinating hobby." Boxes like this rarely survive, and this one tells the whole story at a glance.

It's paint-your-own charm at its sweetest: pour the slip, pop the seals, and decorate them any way you like — the box itself promises "painted decoration on detailed mold." The little family (largest seal 3 inches long, baby just 1-1/2 inches) is made for shelves, beach-house décor, gifts, and studio fun.
