Pitcher by Karl Martz, 1934.
This pitcher can be seen in a 1934 photograph of Karl working in front of the Brown County Pottery.
Collection of Becky Brown. Photograph by Eric Martz.

Karl's signature is of interest because he did not sign his own name or initials. The black "KM" was added many years later with a marker pen. This pitcher has been in the Martz family collection since Karl made it, and hence is known to be authentic.
