57 years.
Two books with "USA" set in black type on their covers, separated by 57 years, almost identical in size.
One published by the Museum of Modern Art in 1952, with slick photography by Julius Shulman and stories about a new kind of American architecture: buildings as shiny objects, walls of glass. Fittingly, picked up in the bookshop at Philip Johnson's Glass House in New Canaan, CT (featured in the book). Could it have been his copy?
The other is "Provisional: Emerging Modes of Architectural Practice USA," edited by Elite Kedan, Jon Dreyfous and Craig Mutter and published this month by Princeton Architectural Press. Less about the architectural object and more about practice and process, featuring some hot folks. Beautiful design by Project Projects and worth a look.
