Below is some trivia about Pringles chips, which Kellogg said it will buy from Procter & Gamble for $2.7 billion.

—The chips were first test marketed in 1968, then went on sale nationally in 1971.

—The chips are made from a dough that is just 42 percent dried potatoes; the dough is cut and placed on carriers, fried and seasoned on one side.

—It takes about three or four potatoes to make a can of Pringles.

—The chips got their name after a Procter & Gamble employee noticed a street called "Pringle Drive" in Cincinnati; the name had a cheerful, nostalgic sound that executives felt paired well with the word "potato."

—The chips were packaged in cans to preserve the freshness and the shape of the chips.

—An artist created the mustachioed man on the can.

—The man who designed the Pringles packaging system was so proud of his accomplishment that a portion of his ashes were buried in one of the tall, circular cans.

—Two-thirds of Pringles' $1.5 billion in annual sales comes from outside the U.S.

—Most Pringles versions don't contain beef or pork derivatives. But some of Pringles Baked Stix versions contain animal by-products for flavoring.
