I can't find an image of Milton Glaser's complaint poster.
(Note: This solution is a Wolfsonian staff intervention)
Milton Glaser's poster can be viewed on our blog, as can others in our poster exhibition Complaints! An Inalienable Right, curated by Steven Heller. Each day we're showcasing one poster online, until we've posted all seventy-plus pieces. The posters will also be on view at The Wolfsonian beginning March 20. Milton Glaser's poster, Pick One, kicked off the online exhibition, so to view you can either scroll down to early blogs or use the Posters filter. Enjoy the show!
