These bars fill an entire page of A. On the previous page, Chopin wrote cresc. in bar 469 and marked its range with dashes until the end of the page (bar 474). The dashes appear then on the next page, from bar 481, yet there is no mark to which they could refer. It proves Chopin's mistake – either a new mark was supposed to be written in bars 475-480 or the composer forgot to write dashes extending cresc. from bar 469 in these bars. The latter seems to be much more likely, since the discussed bars continue the regular ascending progression, which started together with cresc. in bar 469.
