EE1

The authenticity of the small slur running from the grace note and visible in FE (→EE) seems questionable. Chopin would not write conventional small slurs combining grace notes with main notes. It is also unlikely that it could be a vertical slur meaning an arpeggio, since the very grace note repeats the preceding semiquaver. It could be an erroneously recreated tie to c2.
