This page has a few different things on it. The top item is a TMNT cereal sweepstakes flyer that was in the boxes of cereal. The flip side of it has a message stating something like, “Sorry, you didn’t win.” Not sure what a winning piece stated since I didn’t win.
The two comic strips were not specifically TMNT comics but, given that the TMNT were mentioned or alluded to, it shows the impact they had to pop-culture.
The picture in the lower right was likely something I cut out of a magazine or Previews-type publication. One of my favorite TMNT scenes though.
