Anotations

Scope note:

Small printed cards on coated cardstock having a glossy surface resembling porcelain, usually bearing tradesmen's advertisements and often images. They may be lithographed or printed in combination with hand painting for metallic details. Production ceased in the late 19th or early 20th-centuries because the materials contained lead, which was toxic to the printers and painters who made the cards.
