it is a grand indoor boulevard taking us from the central piazza. if you look at the national gallery of art in washington, d.c. from 1940, the same plan that makes it user friendly, the grand stair takes you up to the second floor and the ground floor is free for vehicular entrance and the staircase leads to the main rotunda, your town square. you get your orientation, check your coat, whatever you need, and then the national gallery has beautiful indoor sky lit boulevards that take you in both directions to smaller piazza centers, sky lit, landscape and had where they have indoor concerts. no matter how do you the galleries in the national gallery of art, once you fall back into the sky lit central circulation system you know exactly where you are. this is brilliant planning. these why this, are so american, so pragmatic, so practical, very much for mass society. we built not for the upper 1% or the bottom 99%. we are for the 100%. we built for everyone. the same skill we apply to public buildings we apply to something new on the entertainment hor

italian square and piazza. those bridges i mentioned that carried that subsidiary corporate space you could present, they are held up, well, they look like they are. they are held backup. those are caricatures of the people involved in the construction of the woolworth building. now, roy told me who this was but i don't know and he's looking at a stop ticker so i bet he's the head of irving trust which was the bank that gave them the mortgage and occupied the second floor of the shopping mall. the two that everybody photographs and again they are all foe, the two they photograph are cass gilbert, the architect. cass gilbert in the medieval manner. holding up his wool worth building that he designed. on the right, f.w. woolworth, counting his nickels and his dimes. that is the beauty of the era, you know. they could give us transportation complexes, skyscrapers, amazing glass box department stores, yet they could have fun. the trouble with modern design it does not have fun. the result was by the 1910s we are th
