For part 2 of Andrea Kirsh’s new catalog roundup featuring African American women artists, she looks at “Nina Chanel Abney: Royal Flush,” from the painter’s 10-year retrospective at Duke University’s Nasher Museum of art, as well as at the double-volume publication that resulted from last year’s blockbuster “We Wanted A Revolution: Black Radical Women 1965-1985” at the Brooklyn Museum. Kirsh reflects on generational shifts and on all the work yet to be done.
