I love this calendar - the description said that the printer had to wear sunglasses and described it as "the most vulgar thing he'd ever seen". I have a soft spot for Cooper Sans (geek!) so I think May is my favourite (middle left, diagonal stripes). Love January and June too. And neon's so this season too! Apparently August was printed onto silk scarves that were dropped from a light aircraft onto a beach in Italy.
It's so sad that googling his name now brings a page of obituaries, rather than a page of inspiring and exciting work, like this, these, this, and this.
