Primitive Vintage Hand Painted Be Mine Snowman Heart Shaped Cake Pan. I've been collecting these vintage heart shaped silver cake pans and thought why not try to paint it up and make it into a fun decoration! LOVE LOVE LOVE this! I've painted inside the cake pan an adorable winter/Valentine's design. A snowman holding a heart and the saying is Be Mine. How could we turn that offer down? Heart pans will vary slightly..but all are an average Size of 8"x8 1/2". Hand painted, designed and signed by Heidi.
