Award-winning artist John Picacio told his Facebook readers he will stop displaying art at cons that don’t have a policy of making immediate payment:
As of today, I will no longer participate in convention art shows that don’t pay their working artists their earnings upon exit from art show. Sasquan the 73rd World Science Fiction Convention: This is not in reaction to you, although I trust you’re able to perform better in this regard than many recent conventions have. Conventions I’ve invested in from earlier this year have still not paid my art show earnings. THIS — this payment model is part of the reason why pro artists are choosing to display their works elsewhere and pass on shows of this model. Most working artists cannot afford to display under these cashflow conditions.
Commenters generally endorsed his stance, though another artist, Peri Charlifu, disagreed that it was a hardship to wait the few weeks most cons take to pay.
Picacio’s demand may stress committees that have not adopted technological solutions, but the person who ran last year’s World Fantasy Con art show says there is software that is able to determine what each artist is owed once the show is closed.
Also, the acceptance of credit cards is also common among conventions now – there are tradeoffs with fees and such, but they eliminate the concern people have of waiting for large checks to clear.
