Underpenny Plane and Cast Iron Museum

It may look like an antiques store—and indeed it is—until you express interest in one of the hundreds of cast-iron objects that line the wall behind the counter on the right side of the store. At that point, Underpenny owner and curator Sung Park will tell you that the piece you had your eye on—a sturdy black trivet, a horse-and-carriage toy, an ornate penny bank—is not for sale. The meticulously arranged display, which also includes a collection of hand planes, is the result of more than 15 years of collecting and represents only a portion of Park's total treasure trove. If you truly have your heart set on taking home some cast iron, however, the items on the left side of the shop are for sale.
