This cake pan probably started life in a commercial bakery. Large size horse shoe shape, 11.5" by 12.5" by 3". There is some wear to the inside of pan, see photo #3. Still in good usable condition. I much prefer these to the flimsy Wilton pans. You could also make an enormous ice mold with this, or use as a centerpiece with greens and flowers. Kentucky Derby party, anyone?
