Art fairs are slowly returning after almost a two-year hiatus caused by the pandemic.   The New York Art Expo 2021, which usually is held in the spring, moved their trade show to October at Pier 36.  This art fair is sponsored by the Redwood Art Group and is one of the largest art shows offer.  This year, their numbers were down significantly to about 200 international galleries and artists.   Still, there was something for every taste and price point.
