in The 
hairpin is written in A between the staves and begins after the 1st R.H. chord (in Af the bottom arm starts as early as at the beginning of the bar). In GE (→FE,EE) the mark was moved to over the R.H. part, which, in this case, does not significantly influence its meaning. The change was most probably forced by lack of space between the staves; it cannot come from Chopin. The slight change of range in GE1 (→GE2) – the beginning of the mark was moved slightly to the right – was intensified by all subsequent editions, while FESB additionally reversed the direction of the mark, which is a frequent mistake in the first editions of Chopin's pieces.
