You are purchasing a 1972 Wilton cake pan of a Christmas tree. The number is 502-1107. The cake pan does not come with its original insert nor its original instruction booklet. I was told most instructions can be found on the Wilton website. The pan measures 11.5 inches at the widest part, 15 1/2 inches at the tallest part and 1 3/4 inches deep. The cake pan is in gently used condition. A nice addition to any cake pan collection.
