K-B Toys co-founder Donald Kaufman had a toy collection that was sold at 4 auctions

His collection of automotive toys has been called a masterpiece, the likes of which the antiques world will never see again.

Kaufman, whose family launched, grew and then sold KB Toys, did more than just collect toys; he breathed life into his collection by building an entire wing onto his Massachusetts home. He never told anyone about the collection’s size and scope – even his children didn’t see it. Kaufman said only about 20 people during the past 40 years ever saw the collection in its entirety.

He has collected for the past 55 years, and is not only an incredible scholar who researched every toy he ever bought, but also a ‘completist’ who has upgraded to a near-impossible level of perfection. He has every known color and accessory variation, down to the type of tire or window shape on a given model of toy automobile.”

the first auction in march 2009 grossed 4 million dollars, the 2nd was in Sept
