Hahahahah. Nice! I found this photo from The ads of the world. Here is photo source.
Here's element light... There are ladder and straw are real because they have shadow. Workers printed red background and image of bottle with FX in production. That red background will glare from Sun. When Night, It won't glare but workers installed light powerless. (save electricity bill, lol. ofc.) I believe they said agency in Toronto, Canada.
Edit: Added Hi-Res photo source. Here is link... The Ads of The World is excellent website. http://adsoftheworld.com/media/outdoor/cocacola_straw_ladder?size=_original
