Our eighteenth Guinness poster by John Gilroy is another of zoo seals using the “Lovely day for a Guinness” tagline. While looking on at two zookeepers taking a break and pouring themselves a Guinness, one of the seals is whispering something, presumably the tagline, into the ear of the other seal.
This one is in my top three. I just think its hilarious, and I have always had this weird thing with seals and sea lions.
