In a time of innocence

The picture above is that of (L to R) Charles Justus Davis and Gordon Carr Davis in their youth. It was taken around the turn of the 20th century around 1900 or late 1899. Gordon was born on June 29, 1896 and Charles was born on September 19, 1897. So judging from their age in this picture I would guess it would be around 1900 it was taken about the same time PBTS was formed.
