It's this one, Roger. I really liked so many of the other entries, which were all very clever. Even the one by Mince had its plus-points.
I realise that Colin, by altering the sign, had technically altered the drawing, (like Tarquin Thunderthighs III did), but that didn't detract from the joke, and it still worked without the defacement. It was simply a yellow-card offence at most. He was still "in the game", so to speak. It's a true artist that transcends boundaries and challenges convention. Anyway, back to Colin, I felt his effort had but one challenger, and that was Rob. Since Rob admitted he's just copied something that Roger had created in the past, I had to rule that out too. In the end, Colin won because he deserved to. Well done Colin.
