Very cheeky billboards in the skies of L.A...

Now here's a 'cheeky' way to start your working week.

Your butt, booty, bum, buttocks, ass or behind, there are so many names for your derriere and it seems there are also many ways to show bottoms in the city's skies, whether it be to highlight health issues, entice tourists to Las Vegas nightclubs, sell jewelry, beauty products, or more obviously, underwear.

Here are just a few examples from the past few years of how advertisers have used people's perky assets to sell their wares and services.

Why Daily Billboard's sudden fascination with posteriors you ask? Well of late they seem to be popping up with more frequency as an eye-catching device and they reminded us of some other examples from our extensive archives which we've never shared here before.

This red bikini bottom billboard was snapped along L.A.'s Sunset Strip on April 2, 2012 and was a clever way to draw attention the female model's wrist adorned with a plethora of expensive gold jewelry from Ippolita.

In the world of advertising they say sex sells, and a more recent example of helping an ad stand out from afar is this flirty billboard for Drai's new rooftop beach club coming to the Las Vegas venue in May, and was again spotted along Sunset Boulevard, this time on April 19, 2014.

It's not always women's pert buttocks that are in the spotlight though, as this ad creative driving awareness of colon cancer and urging regular preventative screening with this male speedo clad caboose was photographed at Hollywood & Highland on March 15, 2014, as part of the 'Love your butt' ad campaign from the Chris4Life Colon Cancer Foundation.

From health to vanity (which is in no short supply in L.A.), and this Ubersexy billboard promising a bigger bum by using a cosmetic lotion was causing a big splash along Hollywood Boulevard on September 20, 2012.

Then there's a range of men's underwear called Rounderbum, designed to save time working on your glutes at the gym and making it easier like the ad says, to get a rounder tushy. This targeted billboard was snapped along the gay-friendly neighborhood of West Hollywood's Santa Monica Boulevard on February 11, 2014.

As you can see, there's all kinds of different ways to benefit from being a little cheeky with your advertising. Daily Billboard is sure these aren't the first, and certainly won't be the last examples gracing the skies of L.A., so stay tuned to make sure you're never left behind for ad creative ideas.
