It is astounding that the Paterno family built 164 buildings in Manhattan over the course of 68 years. For me, one of the most delightful features is that they personalized 40 of these buildings with a monogrammed cartouche, cornerstone, fence, marquee, door, balconette, or face. To date, 69 monogrammed terra cotta cartouches have been discovered across these 40 buildings. See them all, learn how they were made, and how they are being preserved in the new YouTube video below.
