Conceptual artist and entrepreneur Phyllis Prinz has listed her Sag Harbor home for $2.1 million.

Prinz and fellow artist Bob Malkin co-founded Think Big! a now-shuttered New York-based chain of stores that launched a craze for 6-foot-long pencils and 5-foot-tall Crayola crayons from 1979 to 1994. You may remember some of their other products, especially the giant keyboard at FAO Schwarz that Tom Hanks jumped on in the film “Big.”

The 3,456-square-foot home, at 4108 Noyack Road, features four bedrooms, four bathrooms, a spacious kitchen and a screening room. It sits on 1.80 acres and also includes a triangular-shaped pool and an artist’s studio.

The listing brokers are Barbara Lobosco and Lynda Sylvester of Douglas Elliman.

Prinz has also put her Woodstock home, in a converted 10,000-square-foot horse barn from 1865, on the market for $1.25 million. She lives in a four-bedroom part of that home while renting the lower two floors, which have been used as an art gallery, a yoga studio and an office space for “creatives.”
