Etching titled lower left margin "The Chain Gate", signed at lower right margin "John LaFarge". The work, 4 1/4" by 5 3/4" inside the mat opening (8" by 10" simply framed) does NOT appear to be by the famous American artist John LaFarge (1835-1910), though a previous owner wrote on the backing information suggesting that it is by that known artist. It might be difficult to ascertain the identity of the John LaFarge who signed this; John La Farge's youngest son, John La Farge Jr. (1880-1963) was a Jesuit, in the priesthood, and worked decades for racial equality, but there is no mention in his Wikipedia listing about artistic talents. Condition is good, there being some browning around the old acidic mat edges.
