No, not really. "Colonial Revival", also known as "Williamsburg" was quite distinct from "Early American". Picture the difference between a Baker catalog and one by Ethan Allen. "Early American" was the mass market descendant of the sort of "quaint" furniture reproductions of idiosyncratic New England pieces offerred by Wallace Nutting and L & J. G. Stickley in the 1920's. These pieces were copied from or inspired by vernacular furniture,mwith the splayed legs characteristic of Windsor chairs and Connecticut River Valley tavern tables, and the simple sturdy lines of case goods. In the 'Thirties simplified versions of this furniture were produced by small craft workshops and village industries organized by the Charitable groups to give meaningful work to the unemployed. When the style caught on the Ohio River furniture companies like Mersman Brothers further simplified it for mass production. During the War it was practically the only style generally available without priorities, and after the war it became dominant for some time.
