 Many, like, Alfred Stieglitz harboured mixed feelings over New York's skyscrapers, reflected in his famous 1903 portrait of the Flatiron building, and his 1910 work "Old and New New York" that contrasts the growing steel frame of the emerging Vanderbilt Hotel with the old low-rise blocks of the street below.Poets also wrote about the issues, the early Modernist Sadakichi Hartmann describing how "from the city's stir and madd'ning roar" the Flatiron's "monstrous shape soars in massive flight".Artists such as Alvin Coburn and John Marin experimented with producing portraits of New York's skyscrapers, capturing the positive and negative aspects of the modern structures.
