My nomination for most bizarre use of a violent piece of art in an advertising context has to be the one we drove by recently with several images from Guernica. It was only on the way back that I was able to catch the text: (roughly translated) We sell the largest burgers of all. That's right. The advertising pitch is essentially, remember all those cattle massacred (representing humans massacred) when they bombed the city in the Spanish Civil War? Well we scraped them up and put them on your plate. Any of our meat-eating readers find that appealing?
