By the beginning of the 1960s, Warhol had become a very successful commercial illustrator. His detailed and elegant drawings for I. Miller shoes were particularly popular. They consisted mainly of "blotted ink" drawings (or monoprints), a technique which he applied in much of his early art. Although many artists of this period worked in commercial art, most did so discreetly. Warhol was so successful, however, that his profile as an illustrator seemed to undermine his efforts to be taken seriously as an artist.
Pop art was an experimental form that several artists were independently adopting; some of these pioneers, such as Roy Lichtenstein, would later become synonymous with the movement. Warhol, who would become famous as the "Pope of Pop", turned to this new style, where popular subjects could be part of the artist's palette. His early paintings show images taken from cartoons and advertisements, hand-painted with paint drips. Those drips emulated the style of successful abstract expressionists (such as Willem de Kooning). Warhol's first pop art paintings were displayed in April 1961, serving as the backdrop for New York Department Store Bronwit Teller's window display. This was the same stage his Pop Art contemporaries Jasper Johns, James Rosenquist and Robert Rauschenberg had also once graced.[38] Eventually, Warhol pared his image vocabulary down to the icon itself – to brand names, celebrities, dollar signs – and removed all traces of the artist's "hand" in the production of his paintings.
