So maybe you’ve heard…the design genre dubbed Midcentury Modern is popular right now. Those seeking a heady mix of provenance and authenticity should head to Freeman’s this Saturday for the 20th/21st Century Design auction. There’s a treasure chest of furniture for sale, including a coffee table by Wharton Esherick, chairs from Ron Arad and Harry Bertoia, and several white oak pews that George Nakashima designed for a New Hope church in 1961. Paddle, please!
