These were typically small and expensive, thus not given lightly. Judging by surviving examples, six to eight by ten to twelve inches were the popular sizes. Before America began to trade directly with the treaty ports of China, they were the careful work of native cabinetmakers. Molded frames, finished with oil or varnish, were of maple, cherry, walnut, or pine. Made mostly in the more sophisticated towns along the Atlantic seaboard, they were simplified examples of the other frames in vogue from the late Queen Anne years to the start of the Hepplewhite period. Some were without the arched top, but had a well-cut molded frame done in high relief, a simple yet dignified design.
