Three American made hard plastic Santa Claus Christmas ornaments from the late 1940s. The one in the center was made by Bradford Novelty. The two Santas with all white faces are from Shiny Brite, a company much better known for their glass ornaments, but they experimented with plastic not long after World War II.
The last photo is from a 1948 Sears Christmas catalog showing the Shiny Brite Santas, which were sold boxed along with plastic birds (the ornaments weren't made long enough to make a specific box that didn't say "glass"). All three ornaments are in very good vintage condition with little wear and no chips or cracks. Hanging loops are intact.
