United States Mail Steamship Co. (1920)

First, I apologize if this is getting too far off the subject of true stamp collecting, however, I have had this pamphlet for awhile and was always curious whether or not this company actually carried "United States Mail" ... does anyone know for sure?:



I did pull off the internet the following which suggests the company was a dismal failure about a year after it was initiated, so there can't me much of a history on it, although the background is rather interesting:

United States Mail Steamship Company
(not to be confused with United States Line)
The United States Mail Steamship Company was formed in 1920 by the US Shipping Board with mostly a fleet of seized ex-German passenger liners. The company made colossal operational losses and receivers were appointed to examine their accounts. As a result of their findings, the District Court ordered on 27th Aug.1921 that all United States Mail ships be returned to the US Shipping Board. Outsiders were appointed to manage the line under the title of United States Lines.

Well at home under "postal history"
fascinating card, and would be a delight to the right
student in this genre.
Absolutely pertinent to this forum and thanks for posting.
