The 
hairpin in bars 17-18 is written in GC (by Chopin?) in a way that is impossible to literally reproduce it in print and at the same time its meaning is ambiguous. Are the signs supposed to concern both voices of the R.H. or only one (which?)? Not having found a satisfactory answer to these questions, in the main text we adopt a solution applied by Chopin in similar bars 33-36. We also suggest adding a hairpin in bars 19-20. In the remaining sources the signs are absent, except for GE (and EE2) in bar 18.
