This is a lovely pair of Art Deco nude lady in clamshell bookends. They were designed by Oscar Mortens of Mortens Studio and are marked to that affect. Mortens Studio was located in Chicago, Illinois, from 1931 until the 1950s. Oscar Mortens emigrated to the United States from Sweden and became a naturalized citizen after studying at the Academy of Fine Arts in Stockholm and the Berlin Academy of Art.
He won the Gold Medal for sculpture in 1933 for a piece titled 'The Dream of Freedom' from The All Illinois Society of the Fine Arts. This pair of bookends are a nice example of Art Deco design, they are plaster and therefore have sustained some chipping and loss of paint. Please view all of the pictures to get a good idea of the condition.
Measurements are: 5 3/4 inches tall, 5 3/4 inches long and 4 1/4 inches wide.
