Big Superman fan here (my favorite actually), this is a pretty cool art that fits Punk's persona and his pipebomb so well.
It's just a shame he didn't set the wrestling world on fire as the IWC thought he would as the response to him winning the title and taking it with him didn't result in gangbuster ratings. I've read Vince was shocked (no doubt he was expecting Stone Cold like numbers) and then the numbers just got the worse to the point that his highest rated feud was with a part-timer who was happens to be a movie star and The Most Electrifiying Man in the Business (who also happens to be my favorite wrestler), a feud,which he lost.
Detractors unfortunately used this as proof that "Indy" darlings will never be over with the WWE crowd and then Daniel Bryan and the YES! movement basically shouted NO!! to that argument as Bryan got pretty good numbers especially after WM30 (which unfortunately ended with Bryan getting injured and being stripped of the title). So this got me thinking, on paper Punk was more suitable for WWE greatness than Bryan was, they were both great performers but Punk had the edge when it came to mic skills and having a persona and yet Bryan was the more successful of the two when getting casual WWE fans interested.
Sorry about the long post, it's just every time I think about Punk's pipebomb, I get puzzled a bit.
I'd say that last 5 years have been absolutely fantastic for fans of Independent wrestling. With the rise of guys like Punk, Daniel Bryan, Cesaro, Rollins, Zayn and now Owens, Itami and Balor the message has been sent loud and EXTREMELY clear that pro wrestler's don't have to fit that stereo typical "WWE Mold" in order to be over with fans.
Granted there's been a few unfortunate bumps in the road with some key players like Punk and DB but the future still looks bright regardless.
