This is a vintage late 20th century signed and numbered color lithograph print from 1990 done in a medium poster size on heavy card stock of an image originally done in 1988 by Robert Tinney entitled "Computer Architecture". Most of his commercial images were covers for Byte Magazine from the 1970s - 1980s. This particular image was on the cover of the May 1988 issue of Byte Magazine. The estimate is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
