Art fairs can be exhausting. Shuffling around through the crowds, making sure you see everything, rushing to find the best works before they get scooped up by a competing collector, dealer, etc. And with just so many of them on the art circuit calendar (Art Basel, Art Basel Miami Beach, Frieze London, Frieze New York), gallery goers are starting to experience "fair fatigue." That's why Art Dealers Association of America President Adam Sheffer called the organization's Art Show at the Park Avenue Armory last night the "non-fair art fair."
