I'm honestly not sure if this key was made for a giant lock or as a trade sign of sorts, but I love it. In addition to its great oversized-ness is the complete simplicity of the form--an iconic key if there ever was one. I believe it is quite old and is thick and heavy and super satisfying as an object, good for hanging or just propping on a shelf. And a 100% perfect housewarming gift!
7 3/4" long x 3 1/4" wide x 1/2" thick. Great condition, with just the right amount of rusting, definitely with a good amount of age.
