Premise: Have you been building up a collection of Americana over the past 50 years or so? If so, then Mike Wolfe and Frank Fritz may pay you a visit one day. The Midwestern pickers travel across America in search of rare artifacts and national treasures that they can buy from the collectors they visit and then sell in their antiques shops or, in some cases, put in their personal collections. They often have to dig through boxes or piles filled with items that have accumulated over the years, which are often located in such places as barns or spare rooms in the owners' homes. While the guys are willing to buy pretty much anything old, their particular interests include items having to do with the auto industry and classic toys. The enhanced episodes on ``American Pickers: Bonus Buys'' provide extra footage of additional items that Mike and Frank buy while out on the hunt.
