In May of 1936, Simplex began advertising their "increased production" of Servi-Cycles (they really were just cranking up after producing very few bikes in 1935 and only prototypes prior to that). At the same time, many of Simplex's suppliers ran ads in Motorcyclist magazine and others congratulating Simplex on their achievement and welcoming them to the motorcycle manufacturing business. Below are some of these ads from 1936, as well as later ads which ran all the way through the 1960s.
