Press-molded buttons made by Becky Brown in the late 1930's or 1940's, shown slightly enlarged. Molds were carved by Karl Martz, who also formulated the glazes. The orange glazes likely contain uranium. Collection of Becky Brown. Color photos by Eric Martz. In 2019, Becky's collection of her buttons was gifted to the Haan Museum of Indiana Art. Below is an original sales card from ca. 1940. Three or four buttons were sewn onto each card. The card was a linoleum cut print made by Karl Martz. A similar card was marked "75¢". 75¢ in 1940 is equivalent to $13 in 2019. Similar cards (with different buttons) sold on eBay for $225 in April, 2007 and $55 in May, 2008. This card with its buttons was generously given in 2013 to the decendents of Becky Brown and Karl Martz by Fredia Liebhard of Reno, Nevada, USA, in memory of her mother (who purchased the card with its buttons ca. 1940), Barbara Delores Marter Garrotte of Worthington, Indiana USA.
