Peachtree and Doric were two lines made by Homer Laughlin for Quaker Oats which didn't originate from an already existing shape. The Peachtree line was made with a cup and saucer only, both of which have heavily embossed bodies and were modeled in July 1936. Records indicate the Peachtree backstamp wasn't made until early 1937.
Doric, also created in 1936, was made up of a 9" plate, teacup, and saucer. Pieces from both lines are rather hard to find.
