This was a ship of the so called "USSB (United States Shipping Board) Design 1029" known also as "535" class passenger-cargo liner ships from their length expressed in feet. She was built around 1920.
The main particulars of such a type of ship were
Length O.A. 535 ft, 12,599 gross t, one funnel, twin screws, 320 pass (These are the data for a typical ship of the class; some details, apart from main dimensions, may vary from ship to ship.

Thanks Mario! I cannot find anything about this board. Same as https://en.wikipedia.org/wiki/United_States_Federal_Maritime_Board? No fleet list found. Is this board different from the United States Maritime Commission?

Sorry I wrote a nonsense!! The correct name is USSB i.e. United States Shipping Board . If you look for it with Google either you go on wikipedia you find it. I corrected above.
Cheers, Mario

She was originally the BUCKEYE STATE, completed in 1921 for transpacific service. Renamed PRESIDENT TAFT in 1922. In 1941 she became the US Army transport WILLARD A. HOLBROOK and here is where her history gets murky. Planned to become a hospital ship in 1943, apparently that never happened. She was renamed AMERICAN REPRESENTATIVE around war's end, 1945; not all sources note that name, but here we have photographic proof. Apparently renamed WILLARD A. HOLBROOK again, laid up in 1947. Scrapped in either 1952 or 1957, dates vary. So this photo must date from around 1945 or 1946?
