47x45mm. Brass base heart and key made from old tooling in the 1950's. Brass base plated in a rusty black patina finish. Flat and filled in on the back, nicely weighted. Sold by the pair, heart/key. NOTE: you really have to distress this with steel wool to reveal the words and highlights. DO this w a circular motion then shine up a bit w a Sunshine cloth....I've put them on sale so you will try it, they are awesome! Sheesh....the key alone is worth this much! HAVE FUN!
