On a recent visit to the Andy Warhol Foundation in New York, gallerist Daniel Blau was allowed a glimpse of rare, early drawings by Andy Warhol (1928-1987) that had remained out of public view for over 20 years. The 300 drawings, which were completed in the 1950s, will be published for the first time next week.

The drawings stand in sharp contrast to Warhol’s highly recognizable pop art works and reveal a lesser-known side of the artist as a talented draughtsman. The works will be published in a book edited by Blau and are currently being exhibited at the Louisiana Museum of Modern Art in Denmark (on view through February 21, 2013). After another exhibition in The Netherlands, the drawings will be put up for sale, surely a welcomed addition to the highly sought after Warhol works currently on the market.

Blau has a longstanding relationship with the Andy Warhol Foundation and organized his first show of the artist’s work in 1995. He has held a number of Warhol shows since then. From Silverpoint to Silver Screen, Warhol: The 1950s Drawings, which is being published by Hirmer, will be available on January 28, 2013.
