OHP description:

Calvin and Ruby Black began building Possum Trot in 1954 as an attraction for their rock shop as well as an artistic expression. Calvin carved the dolls, each representing someone important in his life, and Ruby made clothes for them. The animated displays were designed to entertain visitors.
