West Berlin paper doll, c. 1950s

There is a larger version of this paper doll page; the one shown here is a squarish 6-1/2 by 6-1/4 inches.
West Berlin was created in 1949 in the post-World War 2 era, of course, and was firmly established with the wall or Iron Curtain that went up in 1961 and lasted until 1990.
Given the style of the clothing and the age of the paper, I would place this version closer to the 1950s. The original, larger page might have been the 1930s, but I'm not sure.
