In 1938, he started a small sign-lettering business out of his parents' home. He had to use a neighbor's phone to speak with customers.
With $75 borrowed from a brother, Mr. Mace rented a corner storefront at 17th Street and Passyunk Avenue. By 1940, he had hired a salesman and two part-time helpers.
From 1943 to 1945, Mr. Mace served in the Army as an artilleryman in the Pacific Theater. He was able to keep the business going in his absence by offering all the profits to his employees.
During the 1940s and most of the 1950s, M&M Silk Screen Printing was across from Eastern State Penitentiary in Spring Garden. In 1958, the name was changed to M&M Displays Inc., and the shop moved to 3300 Maiden Lane in South Philadelphia.
The business moved again in 1980, to the Eastwick Industrial Park, where it remains, run by Mr. Mace's son, Chris, with help from other family members.
During his time at the helm of M&M Displays, Mr. Mace received many awards for excellence in screen printing. He was proudest of his 1986 induction into the Academy of Screen and Digital Printing Technology.
