art : makes an excellent example..
works of art : how do we value them?
details?
the emotion it evokes?
the artist?
lets remove popularity from equation ..
just the artist..
i think : its the emotion it evokes..
the 1st sale of any unknown / new artist...
rest : is just follows or improvement.
coz : i dont think the artist got 'intelligent' if his further works are success as well.
it is name, history + last : 'feels'.
