Here in Oreg I found two old photos at 2nd hand store.
One was 4 x 6 portrait on a young man maybe 30 in nice suit by Dames and Butler studio in SF Cal.It is thick paper.On back it says"John H Spring 1880?"I wonder if date may have been a bit later from look of photo.
Other is a 6 x 8 of man maybe 60. In small script on front is hard to read nameW E Oussomills or similat.On back is written. John H? Spring.It is not clear they are same person,my wife who is better with faces doubts they are, but similar look
