Captain Jim Thorpe, various locations, ca. 1960s.
Lucas Thorpe explains:
My father took these photographs during the sixties when he was a deck officer in the U.S. Merchant Marine. Some are from his time as a cadet at Maine Maritime Academy the rest when he shipped out with American Export-Isbrandtsen Lines. He sailed on break bulk freighters and the ocean liner S.S Independence. He took thousands of slides and these are some of my favorites.
Beyond this set, Lucas has been posting more, so continue on to his blog.
