We don’t yet know if Graf left or was asked to leave. The agency has not responded to requests for comment.
Update: As one commenter mentioned below, Creativity is reporting that Graf is leaving Saatchi when his contract expires in mid-summer to start his own agency venture. This disputes tips we’ve been receiving this morning that Graf is returning to Goodby. Still, after this and the Ty Montague/Rosemarie Ryan news, we’re starting to see a theme here, folks.
