Israel issued this stamp in March of 2000 to celebrate the 250th anniversary of Bach’s death. The stamp itself features a Bach portrait. But the tab of the stamp features an organ façade. It is not possible for me to determine what organ this may be. Others maybe can discern it. Israeli stamps are famous for having as much interest in the tabs of stamps as in the stamp itself. This is the only additional information I could find on the stamp, from Israel Post.
