Poster celebrating the 25th anniversary of ethernet. Background of a blue sky with wispy clouds. Sections of concentric circles in yellow start in the bottom left corner; successive lines are used to list key events in the history of ethernet. The poster also lists ethernet pioneers in different aspects of its development. "ETHERNET" is written in large letters along the length of the poster, with a quotation from Arthur C. Clarke, "Any sufficiently advanced technology is indistinguishable from magic."
