I've got my first paquebot mail. What is actually paquebot mail? A paquebot mail is mailed on a ship, and then dropped off at an overseas port for dispatch. So, the below postcard was posted at sea on R.M.S. St. Helena (a small ship; R.M.S. stands for Royal Mail Ship), and the postcard entered the postal system at Jamestown, St. Helena on February 23, 2011. The R.M.S. St. Helena visits St. Helena, Cape Town, Ascension, Tenerife and Portland.
