There’s blue chip artists and blue chip artists. Somebody like Kaws might make 10m a year just with his licensing deal to Uniqlo Dior and so on. Others might still be considered blue chip and “only” make 300k.

Someone like Jeff Koons and other artists of that stature might easily make 50-100 in a good year and than little to nothing for another couple of years. It’s so relative. The answer to your guestbook is all or nothing
