There are not too many poster designers I could name off the top of my head - mostly because the only person I think about is Jason Munn. His work as The Small Stakes always tickles my fancy and it blows my mind that someone can do so much work in the one aesthetic and have it be amazing every time. It's also a bonus that all of the bands he designs for are pretty gosh darn cool.
Chronicle Books have taken it upon themselves to recognise this nice mans nice work and are putting out a book on his posters. If you preorder from here you'll score yourself a signed copy complete with a letterpress print of a new design. This little duck had herself on the list weeks ago - you should do it too, so we can bask in that new book glow together come April.
