In FE (→GE), the engraver placed two separate 
hairpin marks – the former in bar 448 and the latter in bar 449. It must be an inaccuracy of the engraver (cf. the marks in bars 450-451 and 452-453), most probably caused by the fact that in FE bar 449 a new line (missing endings of such elements of notation as slurs, dynamic hairpins, particularly when transitioning to a new line or page, are a frequent mistake of the editions). In EE, the reviser justly placed one mark. We suggest beginning the hairpin right after the 
mark.
