Andy & Vit-C, I apologize for letting your message linger so long without a response. I collect all the boxes for the cereal premiums that I enjoy. That is not to say that I have boxes corresponding to my cereal premium collection, it means that I would like to collect them all. I am more interested in the offers on the back than I am in mascots or flashy fronts. That said, the boxes that I do own are mostly from the late 60's & 70's because that's where the majority of my cereal premium collecting is focused. Freakies and Kellogg's cereals had the best premiums at the time so that's what I have most of in my collection, premiums and boxes.
