According to AdFreak's Rebecca Cullers, this ad is up in Elizabeth, Pennsylvania:

The ad is one of a kind and was paid for by Elizabeth Forward High School, which held a design competition for students and chose four winning boards. JT DeMarco, a junior, created the Grumpy Cat design with some great concepting and a poor grasp of copyright law. 

Grumpy Cat, AKA Tardar Sauce, is a bona-fide internet celebrity with a permanent frown "due to feline dwarfism and an under bite". No word yet as to whether the school has been asked to take the board down.
