A photo from the U. S. Steel owned limestone mine in Yellow Dog, Pennsylvania (Shadyside Village).  This photo is from 1919, beyond that I only know the name of one man and the nickname of another.  From left to right the third man kneeling is John Clair Ruffaner, the man standing behind him in bib overhauls was nicked named "Addie".  A copy of the original that belonged to Clair Ruffaner.
