The catalog from the 2011 DADA Exhibition is now available (pdf) and provides some fascinating information about alumni in design.
Canaan architectural blacksmith Dimitri Gerakaris '69 (art-metal.com) created the copper pediment atop the Rockefeller Center porte-cochere, the Rugby Clubhouse interior bas-relief, and the railing outside Baker's 1902 Room.
The poster was designed by Emily Yen '10 of Hanover and Anchorage.
Thanks to author Sue Reed and to DADA for permission to post the catalog.
