Well, you learn something every day. On a recent DVD of "Little Britain", a joke was made about Golden Wonder Crisps. Being a true American, I had never heard of that brand, so I looked it up.
On www.goldenwonder.com, they talk about the products history and how it developed from 1947 to the present and have some adverts from the past. Great stuff!
Anyway, I guess we're just stuck here with Pringle's and Lay's in the good ol' USA!
