Cheerios (Tumbler Offer) Box Flat: Although Cheerios was plugged for kids, I always found this to be a lame cereal. Maybe the lack of sugar had something to do with it. In addition to be a lame cereal, its box was a rather dull generic yellow design.

General Mills decided to make a ton of different Cheerios boxes with Star Wars offers. The interesting thing here is that this is a box flat, i.e. a box that was never constructed. Try finding one of those for 1970s cereal boxes, particularly Star Wars cereal boxes.
