I would call this poster 'hilarious' but hilarious doesn't seem "hilarious" enough. Maybe if there were more 'pop' it would be more playful and animated in a way that will appeal to the target market. Maybe a couple of graphics that say "It's a mild summer day on the Irish coast and you're opening your favorite book book but you can't read a damned word because it is in italics."
I guess I'm not as Irish as I thought since I have no trouble reading italics. If you are also capable of reading italics and enjoy a poke of fun aimed at ridiculous feedback, take a journey to Sharp Suits and get your fill of fine design brimming with preposterous words.
