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!)
