Trust me, even if you’ve been looking at art for a long, long time (or even longer than that), you will see work at the Art Show at the Park Avenue Armory you have not seen before, by artists you may never have heard of. This is not because the Art Show, organized by the Art Dealers Association of America to benefit Henry Street Settlement, is dedicated to showing the young and hip. Quite the opposite, ADAA represents blue-chip galleries that show high-quality work.

But it has a terrific roundup of art by lesser-known artists, many dead or left out of art history for all the ordinary reasons (gender, geographical location or the idiosyncrasies of their work at a given moment). And despite the density, the fair is very manageable compared with other mega-fairs in New York.
