the first norton logo was a fairly simple, art nouveau design, with the name spelled in capitals. however, a new logo appeared on the front of the catalogue for 1914, which was a joint effort by james norton and his daughter ethel. it became known as the "curly n" logo, with only the initial letter as a capital, and was used by the company thereafter, first appearing on actual motorcycles in 1915. ethel norton also did some testing of her father's motorcycles.
