Gallery artist Knox Martin's painting Woman Seated in Red Chair (1977) is included in the group exhibition Essentialism curated by Frank O'Cain at The Art Students League of New York. 

“Pulling from The League’s Permanent Collection, this exhibit is not about the new — but the essential. It is about finding a way to see artwork through the inspiration and motivation of the individual creator, and to share in their delight of visually organizing and expressing all forms of ideas.” – Frank O’Cain, Instructor
