Numbered Lithograph with a Musical Motif

 I bought this for myself several years ago and never had it framed. The background is much more white than the photo shows; more like the last photo of the lot. It is numbered 27 / 75 and the artist, to the best I can tell is Middlerton , 1972. 

  I have never researched this , I simply bought it for the color = it was and I stress was, right for the room.
