National Historical Landmark-McGraw-Hill Building

The McGraw-Hill Building (1930-31) is the last of the pace-setting skyscrapers in New York by Raymond Hood.

The blue-green glazed terra-cotta blocks that give the building its distinct character represented the largest application of this material ever tried on massive walls.

The International style design is related to the Philadelphia Savings Fund Society Building of 1932 by Howe and Lescaze.
