Coca colas subversive messages ;-)

Apparently this poster was released in the mid 80s. Then there was a total recall of all posters because of picture painted in icecubes at bottom right corner. The graphic artist who designed the picture put this in as a joke, it went through unnoticed until someone spotted it on the back of a coke truck.
An expensive yet somewhat exhilarating joke don´t you think?? If you wish to bid on the poster just follow the pictures ;-)
