Caution: if you are easily offended, I would stop right here. These images may upset you and would be giving the artist the satisfaction of generating more hysteria. However, if you are anything like me...read on!
Provocation is a good thing. Let me clarify, provocation in a satirical way that challenges our own perceptions is a good thing. We absorb it every day in media and advertising. Most see it and are completely disgusted. Some see it and absolutely connect with the inventor's vision.
I always wondered where exactly did sarcasm, exaggeration, and satire originate in art. The answer may be found in the 15th and 16th centuries. There may be earlier examples, but this period prompts a movement that countered the Renaissance's representational art. Some of the best and early examples are da Vinci's "grotesque heads" from the 1490's. While they may not have been created with derisive intention, these were by no means celebrated works and whatever his true intention was lost on the majority of audiences. Their disgust, however, did not stifle the movement for a moment and the practice continued into the 16th century, evolving into what we know as caricatures.
The word caricature originates from the Italian words carico and caricare, which means "to load" or "exaggerate". In the 1590's, Annibale and Agostino Carracci applied these terms to the pen and ink portraits they created. In a sense, these works became a satirical view of their own fine art theories they taught at the Bologna Academy. According to Constance McPhee, Associate Curator at the MET, they laid the foundation for artists who "saw that selected components distorted without obscuring the identity of the subject." But(t), at some point it transitioned into the realm of being highly offensive to most and many of these artists chose to remain anonymous and unconnected to their works (probably for the sake of career preservation).
The Brughels, and others in their era, expanded the practice by creating art that shocked and inspired in the most surreal ways.
Then the 18th and 19th century arrived, where engravers and print makers produced images that truly antagonized people's views and tormented cultural norms.
Today, "offensive" art is created in the reflection of the ridiculous and distorted imagery that was unconventional at the time. And, as our culture continues to transform, a subculture of artists will be there to disgust and horrify you every step of the way. So, I believe you can thank da Vinci for that Tampax ad and any other imagery that you consider appalling.
