Housflag of the Red Star (packet) Line when it was established and run by the New York firm of Byrnes, Trimble &amp; Co., 1821-1835/36 (not to be confused with same-named Belgian/US-American shipping company established in 1873, that used the same flag). The white background colour of the flag was changed into blue, when the Red Star Line was bought up by Robert Kermit. The Line went done in 1868.
