Ant-Sized "Ant-Man" Billboards Pop Up in Marvel Marketing Stunt

With the imminent release of "Avengers: Age of Ultron," the next chapter in the Marvel Cinematic Universe, Marvel has stepped up its marketing for July's "Ant-Man" with a series of tiny yet detailed billboards for the film.

A few of these billboards, which reportedly come with battery powered LED lights for nighttime viewing, have cropped up online via ScreenCrush. They have only appeared in several Australian cities, including Brisbane, Melbourne and Queensland, so far. The billboards are adhered to the surfaces they're on to prevent passersby from taking them home.

"Ant-Man" opens on July 17.
