You are purchasing a 1971 guitar cake pan. The pan is made by Wilton and is number 502-925. The pan measures 17 inches long by 8 1/2 inches wide at the widest part and about 2 inches deep at the deepest part. The pan has no insert, but I am told you can find the instructions on the Wilton website. It has a few scratches and a couple of small dents, but shouldn't affect the decorating of the cake.
