NOS 1920s antique Pre War Silk JAPANESE Meatball Flag 39" X 28" For Sale

Up for sale is a pretty rare find. This is a NOS never used Japanese flag from I believe the 1920s. Based on the map of Japan shown on the box, with the Koreas occupied but not china I believe this is pre 1930s. Japan occupied Korea after 1910. So it's somewhere in that zone. Unused but does have some pulls in the silk. Comes with the original insert sheet as well. Measures 39" x 28". So it's a bigger flag. If you have any questions please feel free to contact me at any time!
