Guinea-Bissau, Mozart Memorial

 

Guinea-Bissau issued this stamp in honor of the birth of Amadeus Mozart in 2016, the 260th anniversary of his birth. The stamp pictures a musical salon scene with participants/listeners and perhaps a clergyperson in the rear of the scene.  In the background is an inset picture of Mozart which includes an image of a pipe organ. Another performer is playing an additional keyboard instrument, a piano or harpsichord perhaps. The stamp seems to show a fairly specific organ, though I cannot determine what instrument it may be. I would be happy to hear suggestions.
