The Art of Fugue itself was unfinished but if as the story goes, he died as he was penning the last bar of fugue 15, then he kind of signed himself out in the sense that the notes corresponding to the letters (in German) BACH are spelled as a motif as B flat, A, C and B natural in the 8th to the 5th bar before the final bar which is unfinished. I have no idea if this true. We do know that this unfinished fugue was the last piece he wrote.
