This is a pair of two silkscreens, 

each signed in pencil: Graevenitz 74, and numbered (one 47/50, the other 50/50), 

from an edition of 50, red and blue on white cardboard, size: 54 x 54 cm.

For this pair of silkscreens Gerhard von Graevenitz worked with a mainframe computer assisted by Rolf Wölk, and computer-generated motifs. 

Very nice example of computer art (algorithmic art/generative art), in very good condition. 

A fact sheet will be issued by the Heike Werner Galerie.

Price includes German VAT.
