Ceramic Nude on a Clam popular Shell

Vintage ceramic piece, nude on a popular large half clam shell. I believe this is a hobbies creation made from 2 pieces. The dish is marked Atlantic Molds. The figure may be Holland.

It's an impressive piece, amazingly unbroken. There are no real problems, some uneven glaze. Measurements: approximately 7” high, 14 1/2” wide, and 11” deep.

I was wondering if this was an interpretation of the birth of Venus….
