The sale was its Signature Decorative Arts & Design and Gentleman Collector Auctions at the company's Design District Annex in Dallas.
"The Forbes property was 100% sold," said Nicholas Dawes, Vice President of Special Collections at Heritage, "and most lots went well within or above estimate."
The collection was split between two auctions, held back-to-back during the day, with most offered in the 'Gentleman Collector' afternoon event, which featured diverse property from several other American and European private collections.
This included a fine group of vintage walking canes, an important collection of motoring mascots, exquisite French boxes, ocean liner memorabilia and a fascinating group of period decorative objects related to the sport of golf.
Malcolm Forbes titled this main collection "Mortality through Immortality," a variety of objects commemorating and celebrating long-gone - and long-forgotten - heroes from distant historic, military and civic endeavours and events.
"It was his personal time machine," said Dawes, "able to transport you to a precise moment in history through tangible contact."
The most spectacular sale was an American union porcelain works centennial vase. Listed at just $6,000-$9,000, the colourful and spectacular piece eventually sold for over five times that at $47,800.
