I did this badge at FC 2016.
For my own amusement, I drew a 'painting' on the wall in the background. I honestly thought no one would know what it was, or pay any attention to it at all. But it made me smile.
However, when showing it to my fellow artists after it was done, I asked each person if they knew what the picture in the background was.
Every one of them said 'Dogs Playing Poker'. (And said it in that tone of 'well, DUH', too....)
Well, I just could not believe it. I mean, this badge is 3x4". That little scribble is VERY small, and not exactly detailed, ya' know?
But they all got it. And the client loved the piece...and also recognized the scribble.
It still makes me laugh tho.
