The one I have right now is the one I remember from when I was a kid. At some point someone no doubt thought that the illustrations could use a bit of touchup and the more recent printings are different. What I'd like for you lot to do is pick which Mr Grumpy you think I should go with.
As for my own personal take on it....I like the newer, brighter colors of #2, but he looks like he's constipated rather than pissy. #1 is a bit faded and pedestrian in comparrison, but I can just imagine him saying 'And what the fuck do you think you're doing, asshat?' and that's spiffy.
....Grumpy #1...........Grumpy #2
Which userpic do you prefer?
