I'm researching some old prints and posters before I put them in the shop. This is an old Mitsubishi shipping agent's wood block printed poster that I think dates from between 1873 (when the Mitsubishi name was adopted) and 1885 (when it merged with another company to become the NYK line) . The red panel shows the names of all their ships. Prints in this period had become very bright as new inks were introduced from the west. This red (or even brighter) is typical of Meiji period prints of the late 19th century.
