Carefully crafted by engineers and often stolen by secret agents, blueprints have come a long way since their introduction in 1842. These master plans printed on four tumbled marble coasters combine to form a detailed aerial map of your new neighborhood, childhood haunt, or favorite stomping ground. Placed throughout the house or showcased in the optional stand, this blue-hued quartet of architecturally drawn drink companions puts your chosen spot on the map and your delicate surfaces at ease. Made in Rhode Island.
