A 10-hole Chromonica I De Luxe For true collectors! As it was an early production model, it was produced in limited quantities and is rarely found today. This is almost a unique product, especially with the original box. At the beginning of the 1950s Hohner came out with two new models, a 10-hole Chromonica I De Luxe and a 12-hole Chromonica II De Luxe. In the late 1940s, John Vassos was hired by Hohner to design harmonicas and accordions with his signature modernist and streamlined aesthetic, primarily aimed toward the American market. Vassos’ design drawings feature marks resembling air whooshing past his harmonicas—musical spacecraft traveling through the galaxy of his imagination.
