Giant Boardwalk Empire season three TV billboards...

Poor Jimmy. His shock death in season two proved that you really can't be half a gangster in the world of Boardwalk Empire.

This super-sized ominous-looking season three teaser for the Prohibition era crime drama, starring the Golden Globe-winning Steve Buscemi, makes for a pretty compelling visual towering over L.A.'s Sunset Strip on August 2, 2012.

If you're a fan of the gritty HBO series, be sure to check out Boardwalk Empire's first season billboards and the show's sophomore season billboards.

UPDATED: After this dramatic giant tease you knew that the official season three billboards were on their way for Boardwalk Empire and here they are.

A wonderful supporting character for the majority of his career, Daily Billboard wonders if Steve Buscemi ever thought he'd see himself up large like this on a promotional billboard as the star of his own highly-acclaimed TV series.

The standard landscape billboards were spied along Sunset Boulevard and Fairfax Avenue on August 21,  with the enigmatic super-sized version snapped on August 23, 2012.

And although 'You can't be half a gangster' makes for a great season tagline, Daily Billboard is sure that by sawing some mobster in half to send a message you could technically be 'half a gangster'.

UPDATED: Here's more billboard support for the show's third season from Times Square in New York City on August 28, 2012.
