We all know that everyone can make mistakes. And apparently, even the comic book writers of this well known comic book, Marvel, are not exempted from this. Mistakes just like these can be caused by many things. I personally think that these bloopers were probably caused by tight deadlines. But readers must give credit to these writers, because despite those tight deadlines, they were able to meet them. And these writers surely did an incredible job of laying the groundwork for the high quality comic books we have today.
