On any given day, about one in eight Americans eats a delectable slice (or two, or three) of pizza.
Once the pie is gone, most people toss their pizza boxes. But pizza aficionado Scott Wiener of New York City doesn't just seek out a good pie; he seeks out the boxes they come in.
Wiener has about 750 pizza boxes from around the world, many of which are featured in his new book, "Viva la Pizza!: The Art of the Pizza Box" (Melville House).
Scott Wiener, who gives tours of notable New York City pizzerias and also blogs about pizza, has boxes from 50 different countries - from Australia to Thailand - in what the Guinness World Records has declared is the world's largest collection of pizza boxes.
Wiener's obsession started when he was traveling in Israel seven years ago, where he saw pizza boxes much different from what he was used to in the States. "Just seeing something that's a familiar image with an unfamiliar presentation totally rocked me," he told CBS News' Serena Altschul.
Then he started collecting box after box.
The Winking Chef
The caricature of a smiling mustachioed chef has been a popular feature of pizza boxes for decades. Sources say it dates back to the 1950s, to a hand-painted sign on the roof of Schaller's Drive-In in Rochester, N.Y., though some claim it dates back even before World War II.
Boxes To Go
Freeport Paper on Long Island produces about 10 million pizza boxes a week, and ships them all over the world.

"In the early years, there was always an old-fashioned pizza guy with a big mustache in front of the box," said Gil Korine, the president of Freeport Paper. "In more recent years, it kind of went into more of a cafe design."

Seran Altschul asked, "Are you a pizza fanatic?"
"I prefer the term enthusiast," laughed Scott Wiener. "I feel like 'fanatic,' there's maybe something emotionally wrong with you?"
"So you're saying this isn't an obsession?"
"It's definitely an obsession, but I think there are healthy obsessions and unhealthy obsessions. Hoarding is an unhealthy thing, [whereas] this brings joy to people around me."
