Small photograph, approximately 3-1/2+" by 2-1/2", of two men identified on the face as Hebert Sparks and Earnest Silvester.
It's possible these were misspelled names for Herbert Sparks and Ernest Sylvester. Nothing on reverse.
The photograph was found with a collection of photographs from mostly Maine. Interestingly, Varney Cemetery in Brunswick, Maine, contains graves for:
This Herbert, a native of Small Point, Maine, was raised at Bath, Maine, and worked at Bowdoin College in Brunswick, Maine, for many years. The Bowdoin President's Report for the Year 1967-1968 included a brief obituary for him.
Ernest may have been the George Ernest Sylvester mentioned as Brunswick Fire Chief in the Bowdoin Alumni Magazine issue of October 1959.
If you recognize either of these men from family photographs or research and can make a positive identification of at least one of them, please leave a comment or contact me directly.
