Vintage New York Postcards, Part 1. The first time I saw vintage postcards of the famous skyscrapers of New York was in Rem Koolhaas’ book Delirious New York, A Retroactive Manifesto for Manhattan. Written in 1978, the content was breathtaking in its idiosyncratic way of writing on the emerging metropolis. Beyond the beautiful Sandborn map featured on the inside of the cover, I was enamored with Koolhaas’ inclusion of many iconographic images of old postcards documenting historical NYC buildings. Later, after living in the Big Apple while a student of architecture, I started collecting those picture postcards, which ultimately developed into a serious hobby, which has a name: Deltiology.
