For our very first project in my art/methodology class last semester, we were told to find an advertisement, preferably a vintage one, to deconstruct and "talk back to" in a work of art. My research in particular took me to the 50's--the age of Sputnik, the Cold War, and all things retro. It was a good time to be alive--that is, as long as you were a white, middle-class, heterosexual man.
To say that just a lot of those ads were sexist is an understatement. Whether they were sexual in nature or had to do with the message of living submissively in the household, every ad had some unique way of degrading women. The one I wanted to do was a wine commercial, hence the wine glass. The "wine" in this painting is meant to serve as a symbol for all the repressive laws and gender roles that have been ascribed to women since ancient times. As you can see at the top, the woman doesn't seem to like it, but drinks anyway.
The panel in the middle is a transition. In recent times, women decided to start thinking for themselves and fought for their independence, hence the spitting action. The glass shatters on the ground. What's left of it still remains a little, but for the most part, women can start leading less repressive lives.
For a long time people in patriarchal societies thought less of women just because they were women. It was as if they were born ignorant, weak, and dependent, and so they were expected to behave that way. Gender determines our roles, not our biology. Regardless of who and what you are (and I speak on behalf of EVERYONE), you have feelings and free will. Take advantage of that as much as you can, and don't let anyone tell you that you're worthless and helpless.
