NEW YORK & LIVERPOOL UNITED STATES’ MAIL STEAMSHIP CO.

The steamship line changed its flag about 1855. Rosanoski’s copy of Bonsor makes both versions burgees, or swallowtailed flags, and does not say that the shield on the second flag was angled.

Rosanoski considers the rectangular FOTW rendering incorrect because Bonsor specifies a burgee, unless the 1975 reprint changed the earlier editions. The funnel is assumed to apply; it was not supplied in that flag source.

The New York & Liverpool United States’ Mail Steamship Co. was formed in 1848. Sources date the start of operations to 1849 or 1850, with the latter account giving an operating period ending in 1858.
