Bruce G. Waugh, 1975
This one features two different stamps from the same contractor in the same year. For the first time I felt compelled to search for a contractor. I found an obituary for his wife, Joe Ann Waugh. From it I learned a bit about Bruce:
[Joe Ann] met Bruce during a visit to the Santa Monica pier during WWII. After marrying the couple settled in the Los Angeles area and founded a rake manufacturing business. During one of their numerous selling trips, they discovered Santa Cruz. In 1963, they relocated to Santa Cruz where they operated a concrete contracting business until their retirement in 1985.
