I have only one of these beautiful gold pins and can put any type of typewriter key in the center that you would like. There is an antique brass lace bezel setting ready for the key of your choice. Pin is vintage gold cast metal and measures 3 3/8" long and 1 3/4" wide. Very ornate! Perfect holiday pin! I show the pin with a letter J set in, but you may choose any letter. The key may be black or white.
