classic motorcycle forum

First, let me say that my grandfather must has made a mistake when he labeled the back of this picture "Leslie & me in 1906" when it was taken and printed (not later on when he was old).  I would be happy to email you a picture of the back of the picture.  Second, I guess the picture does exist since it is posted on the site.  Third, I just looked at an advertisement I found for a Yale Test motorcycle that looks similar to this one dated 1901.  Fourth, since the picture shows one of the sawmills that he kept the books for in 1906, I assumed the motorcycles were from 1906 or earlier.
