Haven't had a chance to really look at the artwork in detail yet but overall was VERY impressed with it. Crispy clear and reminds me a lot of ANS1 (and my favorite ANS sticker, ChimpStick). Very colorful stuff and hope it is a sign of things to come (OS2+ and ANS8+).
The few Wackys that semi-offended me were: 1991 Pigtionary, 1991 Little Dead Kitten, 1991 DuckBar, and ANS1 Gravestones (believe it or not). There's something about the parodies of the newer series that can sometimes have an "edge" of grimness and/or anger that isn't as fun or funny for me as the vintage OS series.
With Little Dead Kitten for example, I don't think the blood is necessary at all. With DuckBar the duck appears really angry as opposed to confused/exasperated, and Pigtionary and Gravestones have a grimness I can't quite put a finger on.
