Most likely this 3 Qt mixing bowl was never used. The perennial collectable that is Spongeware made by Roseville Pottery can be yours. It's the traditional shape with a deep outside rim, blue over tan. It's stamped and signed on the bottom: " Robinson Ransbottom" as well as "Roseville Ohio" and "USA." Very heavy!
DIMENSIONS: 10 1/2" wide at rim; 5 7/8" tall
