I have to say, I love the images, but don't quite grasp the concept... but perhaps you don't need to.
In the UK, it is also widely reported that Kate Moss has two shagging skeletons in her house that she places in strange positions. To each their own!
Implications - Unusual imagery is a great way for advertisements to quickly capture consumers' attention among a sea of visuals. Businesses should consider using shockvertising -- like these skeletons engaging in sexual intercourse -- if they want to stand out from competitors and produce memorable products.
