Very rare blank “On board RMS ‘Titanic’” lettercard stationery, 5 x 8, with the White Star Line name and burgee in color on one side and “On board R.M.S. ‘Titanic’” and the White Star burgee at the top of the other side. These lettercards were designed to be folded and posted without the need for an envelope. In very good condition, with a central horizontal fold, scattered toning and foxing, heavier to edges of one side, and partial separations along border perforations. Blank lettercards such as these are extremely rare and would have been taken off the ship by a survivor, perhaps in a purse or breast pocket.
