"O.W." is published in Punch Magazine
In one of Punch's Fancy Portrait prints, cartoonist Edward Linley Sambourne depicts Oscar Wilde as a sunflower, a very popular symbol amongst the Aesthetes. Sambourne chose to include a quote from the Christy Minstrels, a blackface music group that was popular in the 1850s. This quote is followed by saying that Wilde's poetry is tame, emphasizing that he was more of a popular celebrity and less of an artist and poet.
