This is a promotional bag for National (now Panasonic) fluorescent lights. The age is unknown, but I believe it's from the Showa 50s (1975-1984). Mickey Mouse Size: Approximately 48 x 42 cm As the photos show, there is some discoloration on the ears. Please understand that this has been stored at home for many years. It will be folded to A4 size and shipped via standard mail.
