Can anyone identify this image for me?

The design is obviously an illustration snippet from something.
After taking a peek at some of the 1" button pins offered on Etsy.com, I've come to realize that there is a whole fad consisting of people with button-making machines creating little buttons from just about any random graphic image. There are literally thousands of them!
Here are some random examples:

I was not aware of how many people now have button-making capabilities. In the 60's and 70's, when I was a 'youngster' and wore all kinds of anti-war and groovy button pins, buttons were something only 'official' businesses had the ability to manufacture.
So, times have changed and I know think it would be almost impossible to track down where the image came from. The image is probably just a result of someone's fun moment with their button machine, and likely does not have a 'profound' message like I had thought at first.

But I do appreciate all the good suggestions as to it's origin- it may well remain an enigma. I'll keep wearing it and maybe one day someone will see it and say "hey, that's ____!"
