No, it's not a lost Escher print, it's a photo of Saarinen's long-lost TWA lounge at Idlewild, and you can buy it as a print:
Circa 1964. "Trans World Airlines Terminal. Idlewild Airport, Queens, New York." Acetate negative by Balthazar Korab (1926-2013), Hungarian-born architectural photographer who documented the work of Eero Saarinen.
TWA: 1964 (Thanks, Fipi Lele!)
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
