Native of NYC now in PA
The 1938 World's Fair TRYLON & PERISPHERE
(There may be a room-size model at the World's Fair exhibit in Flushing (the old Fair grounds)
These structures symbolized the city's willingness to 'look ahead...to better times' even as the war clouds were thickening over Europe.
Re a photo: the Fair Museum should have photos and small (souvenir) models ... hopefully they have a larger (room sized) model
