Artist Herbert Hoover, also known as “POTUS31” in a nod to his presidential namesake, creates irresistible small sculptures in pewter, bronze, brass, and silver. Among his most popular is this gleaming cracker. Cast in New York City, it transforms and preserves the familiar perforated square of a saltine in pewter. “No carbs and no calories,” promises Hoover. Each cracker comes tucked inside a box, making it ready for gifting.
