Here's something that make its way under a designer tree or two this holiday season. "Modern Architecture Pop-Up," by David Sokol (a contributing writer for Contract) and Anton Radevsky unfolds architectural gems right before your eyes. Among the folds: the Brooklyn Bridge; London's Crystal Palace; the Eiffel Tower; New York's Flatiron Building; FLW's Robie House in Chicago; Le Corbusier's Villa Savoye; Saarinen's TWA terminal; Gehry's Guggenheim Bilbao; Calatrava's Milwaukee Art Museum; and Foster's London "Gherkin" building.
