We've never really done a beer based post before, so this is a first. Guinness advertising dating back to the 1930s has built a reputable brand image through quick and easy ads that promoted the dark Irish beer in a cheery and joyful way. English artist and illustrator John Gilroy has produced many of these posters, though I'm not quite sure as to which ones in particular he's responsible for. I have to say, for a product like beer, these really do a dandy fine job in putting you in the mood to go out and grab a pint.
Also Guinness's website has taken the liberty in archiving a lot of the ads for both television and print.
