You are purchasing a Wilton cake pan of the 1977 Superman cake pan. The pan number is 502-1212. The pan is licensed by DC Comics. The pan measures about 13 1/2 inches tall by 13 1/2 inches wide by 1 3/4 inches deep. The pan is in gently used  condition. It has very light surface scratches and no visible dents. Sorry, no insert nor instruction booklet included, but most of the instructions can be found on the Wilton website I have been told. A nice, vintage addition to any collection.
