This is for a lot of 3 unused extremely scarce vintage Halloween paper plates, manufactured by Hallmark, ca 1950s or possibly 60s.  These each feature an evil bubbling/boiling cauldron.  Measure 9" x 6". White areas of plates show foxing/toning (they look more white in the photos than they actually are). One has a small chip on the bottom edge where the orange edge shows white. Very hard to find design that never turns up!
