Guinness is a popular dry stout beer that originated in the brewery of Arthur Guinness at St. James's Gate, Dublin. Guinness is based on the porter style that originated in London in the early 18th century. The most notable series of adverts was created by Benson's advertising, primarily drawn by the artist John Gilroy, in the 1930s and '40s. These included phrases such as Guinness for Strength, Lovely Day for a Guinness, Guinness Makes You Strong, My Goodness My Guinness, (or, alternatively, My Goodness, My Christmas, It's Guinness!) and most famously, Guinness is Good For You. The posters often featured animals such as a kangaroo, ostrich, seal, lion, and notably a toucan.
