Sourced from my late brother Joshua Evans personal collection:

This auction is for a 1964 The Beatles harmonica made by M. Hohner of Germany.  The box is in great condition and features images of each of the band members along with their signatures.  The harmonica appears unused and does have what looks like a factory defect - one small rivet is missing from one end resulting in a loose plate.  See the photos for the details.  Measures 4.25 x 1.25 x 1".  An amazing and rare Beatles collectible!
