Beautiful piece of bakeware from the 1940's, produced by the National Brotherhood of Operative Potters out of Cambridge. It appears to be well-loved and used over the years but still has it beautiful floral decoration on the front and red top rim. The style is "Garden Glory." The sides are ribbed and the bottom is stamped.
Bottom reads:"Protected by Design Pat 107564-65-65 - Universal Potteries, Inc. Cambridge, O. - Oven Proof - Made in the United States of America". In the center of those words is the seal of the "National Brotherhood of Operative Potters."
No cracks. Measurements in photos.
