This is an unusual set of four hooks. They are more fancy than most. These Victorian-era hooks have the upper arm platform for the hat and a lower arm, or hook, for a coat or scarf. Each hook protrudes 3 3/4 inches from the surface. The back plate, with four holes, measures 1 3/4 inches by 1 1/8 inches. This set would also look very nice lined up in a row on a board. They are eye-catching!
