This picture used to be on my website, but now it's nowhere, so this seemed like a good opportunity to bring it back to the light...

  

... I had this on my web site because I remember consuming at least one box of the stuff when I was small.  It was just pink-colored Frosted Flakes.  Nowadays, a cereal like this would just be sold for 6 months or so to capitalize on the Pink Panther's (or whoever's) current faddish fame level.  But back then, I'm pretty sure they were trying to create a lasting brand.  "They" failed.
