Description
A bold Guinness advertising image showing Gilroy’s glossy black sea lion posed in profile, balancing a foaming pint on its nose, with oversized red “GUINNESS” lettering cropped at left. The strong white ground and green keyline border give it a clean, high-visibility look designed for instant recognition.
Gilroy’s Guinness animal series became a cornerstone of British outdoor and point-of-sale advertising from the early 1930s onward, using simple visual jokes to make stout feel modern and friendly.
This is the right-hand sheet of 2-sheet poster. Note this is NOT a complete poster.
