I really don’t know what made i ball’s agency here do a direct lift of the idea from such a popular international ad of Australian Post.
Here is the original ad of Australia Post, click on the image if you want to see the larger file.

Updated on 30.09: Just got an email of exchange4media and it announced the winners for some Go Green contest. I believe this ad too had some inspiration from australia post’s ad. You decide.
