In FE (→GE1→GE2), the upper note of the last quaver in the L.H. is an erroneous f
1. What is more, the traces visible in FE prove that the note was introduced in the proofreading instead of the correct g1 (there is a visible trace of g1 on the 3rd ledger line, crossing the notehead, placed slightly too high; as a result, the mistake is inconspicuous). It is the 2nd quaver that provides an answer to the puzzle, in which the correct f1 was also proofread from g1. Therefore, the engraver must have initially printed g1 in both places and then mistakenly changed both notes. The mistake was corrected in EE and GE3.
