The subject of this vintage photographic portrait is Olin B. Clark (1900-1939) and he was photographed by A. G. Churchley of Portland, Oregon. Young Olin looks a bit intimidated by his photo shoot. He also looks very cute in his sailor type outfit. The 1910 US census finds young Olin living with his parents in Portland. His father, William C. Clark worked as a trolley conductor while his mother (Louisa F. Clark) was a homemaker. The 1920 US census revealed that Olin worked as an airplane mechanic in Portland where he lived as a boarder.

A very short life.
Yes indeed. I knew a younger Olin Clark back in the 60’s, and the youngest he could be now would be 85!
This photo so looks like him! I think he may have been a ‘junior” too.
That is interesting. Some genealogical research could tell you whether there is a connection between your Olin Clark and the boy in this photograph.
