Oreo Wonderfilled billboards...

In addition to Apple's Shot on iPhone 6 outdoor ad campaign dominating the skies of L.A. with multiple creatives this month, there's also these fun 'Wonderfilled' billboards for Oreo gracing the city skyline to lift your spirits and tickle your taste buds.

The iconic sweet cream-filled sandwich cookie has been an American favourite for years, so Oreo asked ten different artists to produce illustrations working from words like 'twist', 'wonder' and 'discover', with the only requirement that the cookie wafer was used as a head/face, and for them to 'Play with Oreo'.

These are the groovy, colourful results and oddly all the varying images work remarkably well together as a cohesive advertising campaign.

These standard landscape Oreo billboard ads were spied around the streets of L.A. on March 4, above West Hollywood's Sunset Strip, along La Brea Avenue, Pico Boulevard and Hollywood Boulevard.

The giant-sized version of the 'twist' ad creative was snapped eastbound towering over Wilshire Boulevard in Koreatown on March 8, 2015.

It's nice to see a food manufacturing company having some fun with their brand out-of-home, and if you like these vibrant ad creatives, be sure to check out these Popchips billboards featuring Ashton Kutcher from 2012 and these Ben & Jerry's ice-cream billboards from last year.

Be sure to enjoy these Oreo billboards in the skies (and not just in your tummy) before they are gone and always remember to check your teeth after you eat them, as that's a less than wonderful impression to make when you smile.

Now grab a glass of milk and be prepare to be 'wonderfilled', however you eat your Oreos.

UPDATED: Here's another billboard from the irreverent outdoor campaign, this one referencing the milk that goes so well with the cookie with a basketball 'slam dunk' theme, snapped along Figueroa Street in Downtown L.A. on March 13, 2015.

UPDATED: In addition here's three further cool creatives spied at the Eastown Apartments in Hollywood and nearby on March 16, 2015.

It's hard not to smile when you see these inventive 'Discover', 'Roll' and 'Dream' Oreo billboards and wall murals, don't you agree?
