Norman Rockwell's The Rookie has sold for $22.5 million at auction Thursday. The 1957 painting of baseball players in a locker room was sold by Christie's auction house — heady heights for a work that first appeared on a magazine that sold for 15 cents.

While the "hammer price" of the Rockwell painting was $20 million, Christie's says the painting's final price is $22,565,000, reflecting a buyer's premium. We've updated this post to reflect the auction house's final calculation.
