This monogram was designed by the greatest musical genius in history, the Father of music: Johann Sebastian Bach. Here too, as in much of Bach's music, simplicity forms an admirable and complex beauty. The image is simply, the superimposition of the initials of the master's own name: JSB, with his own reflection; like the countless times he wove a retrograde counterpoint with his melodies. The crown represents that he was in the service of the Elector of Saxony in the city of Leipzig from 1723 until his death in 1750. Because of its age the design is already in the public domain, and does not generate intellectual property rights and we are not aware that it has already been used to create an NFT, so this is surely the first in history, a collector's item that will take on a very high value in the course of time.
