Most high priced art is used for money laundering while entire productions fail at no fault of their own. So no, money is not a measure of an art's worth
If all you care about is money, crank out the most soulless crap that panders to the masses, get into money laundering, or sell feet pics and furry art
I'm gonna sell bespoke gender surgery. Every person a gender of 1, with exquisite Custom-Made genitalia incompatible with literally anything. You'd like it.
no trying to be an ass here, but if you already know your answer (sales numbers), then why ask here? are you wondering where you could get salesnumbers by genre/ artform?
The sales numbers are a pretty objective measure, actually.
Not really. Depends what you sell. I'd much rather sell a single painting of Van Gogh than 10.000 books (which would be considered excellent numbers by many publishers) about the same Van Gogh.
