Two cereal puzzles

I found this White Mountain cereal puzzle on a yard sale for $1. Can't beat the price but they're one inch bigger than my puzzle board can hold. I got it anyway and decided to add it to the pile of things Cindy bought when she was here.

I added it to her pile and noticed that one of the puzzles she bought when she was here was a White Mountain cereal puzzle. Oops.

But wait. On closer inspection, the two puzzles have different pictures of cereal boxes even though some of the cereal included is the same on both. Who would have thought?
