Career choices are important. Imagine if Nicolas Cage never quit his job as a popcorn vendor or Madonna remained working at the Dunkin’ Donuts counter. So what if one of the most notable writers of the XXth century, sir J. R. R. Tolkien, chose to realize his passion for creative writing in the advertising business instead of literature?

A witty Tumblr named “One Ad to Rule Them All” is dedicated to exploring this possibility. A series of make-believe posters feature major brands matched with famous quotes from Tolkien’s literary works such as “The Lord of the Rings” and “The Hobbit.” The ads are a playful juxtaposition of modern brands and not-quite-so-modern text. However, the oft-repeated “You shall not pass” quote is still left uncovered. Can you think of a brand to go along with it?
