Elevated Structure, by August Mosca, Amer., (1905-2003) Softground I've confirmed this from photographsLithograph, 1977, Ed. 20 50, 10 7 8 x 13 5 8, signed, titled and numbered in pencil, on warm white wove Rives BFK paper 17 x 20 7 16. Meticulously printed by George Miller, these urban subway lithographs by Mosca remain true to his early vision of the city. Mosca's dynamic, patterned compositions celebrate the structure of modern transit but steep their precisionist symmetry in a luminous atmosphere.
