British cake brand Mr. Kipling unveiled an poster made of cake today at London mall Westfield. The poster is made of over 13,000 Mr Kipling cakes and spells out the words "Life is better with cake" (the brand's current tagline.) Mr Kipling is giving away pieces of the poster to hungry shoppers so we're assuming it's a one-day-only campaign. While it has given away free slices of cake before, with a cake-dispensing bus shelter poster in 2012, this is apparently the first time a whole poster has been edible. JWT London is responsible.
