Anonymous Sticker

I was just recently (within the past 8months) aware of who the group Anonymous is. I saw their logo online and thought it looked familiar. A week or so goes by and then I saw this sticker in one of our office windows here at work and then it clicked that was why it was so familiar to me. We printed these stickers for a client last year. And had seen it around the shop when it was getting processed and printed and unfortunately the day it came to my department for contour cutting I was out. As for the client? I dont know who he/she/they were. But then again thats how "they" at Anonymous operate right?
