About American Pickers Season 4, Episode 4 : The Pick, the Pawn, & the Polish

Hoping to score big on the East Coast, Mike and Frank make stops in Virginia, DC, and Maryland, and are delirious when they find themselves waist-deep in a treasure-packed machine shop. Harry's property is wired for maximum security and once the guys gain access to his amazing vault, Mike makes a high-stakes gamble. Driving off the beaten path, the guys run across a quirky artist with a wacky sense of humor and a sprawling Virginia property packed with funky collectibles. After wading through building after building, Mike pounces on a one-of-a-kind feline with an impressive pedigree. Featuring the mother lode of "petroliana", Mike and Frank scour a defunct Maryland oil company where everything is for sale. Tim is hoping to make some money to revive a vintage local beer and the guys are determined to help him clear out some of his unique mint-condition inventory.
