The Beatles Harmonica box
Manufactured by M. Hohner, Inc. in the 1960s, this custom 5" box contained a generic harmonica. Two variations of the box exist, the one shown has George's and Paul's names reversed, the other has them correct. The correct version is very scarce and rarely turns up.
The harmonica and box were also sold attached to a 7" x 11" open-up display card (shown below) which featured a picture of the Beatles on the front and songs & music on the inside.
