This is a HOHNER harmonica catalog created in 1975 by Moridaira Instruments, known as the exclusive distributor of "Morris" guitars. The man on the cover playing the harmonica looks a bit like Toshio Moridaira, the founder of Moridaira Instruments... I think. The catalog is a simple, two-fold design, but it's a very valuable document, as it's believed that few copies still exist. Thank you for viewing.
