Every year on 16 June, fans celebrate James Joyce’s 1922 novel Ulysses. All of the events in Ulysses took place on 16 June 1904 as the hero Leopold Bloom – he of the distinctive bowler hat and moustache – journeyed around Dublin. The Modern Library Publishing House named Ulysses as the best novel of the twentieth century (The Great Gatsby was second). There are now Bloomsday celebrations around the globe every 16 June – from Dublin to Montreal, from San Paolo to Melbourne. We have used repeating images of Leopold Bloom on blue green paper as a tribute to the colour of the cover used in the original publication.
