In July 1872, a new postal convention with Switzerland provided for closed mails via Bremen or Hamburg. To differentiate between this convention and the 1870 convention which was for closed mails via England, New York created a series of new circular datestamps. This is one of two different marking showing the desired routing through England and Belgium, "VIA ENG. & OSTD".
