The Sewansecott oyster cans, produced by H. M. Terry Co. (founded 1903) of Willis Wharf, Virginia, are collectible vintage advertising tins that once held salt-water oysters. They typically come in pint or gallon sizes, featuring eye-catching early 20th-century lithographed Native American–style bust logos.

A pint-sized Sewansecott oyster can measures approximately:
* Height: 3.75 to 4 inches (9.5 to 10.2 cm)
* Diameter: 3.25 to 3.5 inches (8.3 to 8.9 cm)
