Is pfaltzgraff ever unmarked

Pfaltzgraff pottery can sometimes be found unmarked, especially older pieces or those produced in the early years of the company. Many items, particularly from the 1970s and earlier, may lack the typical Pfaltzgraff stamp or insignia. However, most contemporary pieces are usually marked to identify their brand and collection. Collectors often seek out both marked and unmarked pieces, as each can hold unique value.
