US Design Patent 148159

I really like this one, issued in 1947 to George P. Gubbins of Chicago. It appears that each hole on the harmonica gives a note which corresponds to the piano keyboard design on the upper cover.

Hohner used a similar idea on some of their Polyphonia instruments, except that the keyboard design was simply embossed in the metal cover, rather than being molded as this one seems to be.
