Based on the New York Mar. 13 and Havre Mar. 26, 1861, dates and 12c credit, this cover was carried on the Adriatic, departing from New York on Mar. 13 and arriving at Queenstown on Mar. 23. According to North Atlantic Mail Sailing 1840-75 (p. 45, footnote 69), the Galway Line's Adriatic was used by Cunard for this eastbound voyage.
Very few covers are known with stamps prepaying the transatlantic rate and carrier fee. This is the second such cover we have seen with 5c and 10c 1857 Issues. (Image)
