Doug Allen, president of Mastro Auctions expects that bidding on a number of the auction items will go well into the six-figure range. More importantly, Allen anticipates that the average selling price per lot will exceed $25,000, more than five times what an average top sports lot generates. "This isn't just an auction, it is a major sports event," said Allen. "It's unlikely we'll see this much fresh, high caliber sports history offered together again any time in near future."

Increasing the excitement of the sale is the fact that it marks Mastro Auction's entry into the Live Auctions arena. Allen admits the creation of a Live Auctions division wasn't on the top of his priorities list upon assuming the lead at Mastro Auctions. "Going once, going twice, sold aren't words I thought would be associated with Mastro Auctions," said Allen.

But with the company's continued success at expanding into other collecting markets, especially in Fine Arts and Americana, and its emergence as a major auction source, the need for a Live Auction component became obvious. "The elite nature and high quality inherent in the items we consistently offer will periodically warrant a live auction environment," said Allen. "And in true Mastro Auction's fashion, we plan to do it right from the beginning with an unforgettable inaugural event." In addition to the rare, possibly once in a lifetime opportunity for collectors to own some of the best sports memorabilia in existence, the Mastro Auctions' Live Sports sale will also offer hope to individuals battling cancer. Mastro Auctions is teaming up with avid sports memorabilia collector and cancer survivor, Jeff Rosenberg of Tri Star Productions, to raise money for LIVESTRONG, the Lance Armstrong Foundation. Rosenberg will be donating some of his personal sports memorabilia for auction. The proceeds of this portion of the auction as well as 100% of the $100 Live Auction entrance fee will be donated to LIVESTRONG.

Rosenberg was diagnosed with testicular cancer on January 9, 2006. After discovering the cancer had spread, Rosenberg was treated and given a very good prognosis. "There is nothing like surviving cancer to make you realize the most important things in life are those closest to you and doing the things you love," said Rosenberg. Passionate about sports collecting most of his life, Rosenberg has embraced the opportunity to raise funds through his beloved hobby to assist others battling cancer. "Collecting while contributing to a greater good," said Rosenberg. "This is the kind of evening I live for."

Prior to the auction on the evening of Friday, August 3, all items to be auctioned will be on display at the Mastro Auctions booth at the National Sports Convention at Cleveland's International Exposition Center. The Mastro Auctions Live Sports Auction will begin at 8:30 p.m. at Cleveland's House of Blues located at 30 Euclid Ave. For more information or to purchase the advance charity admission to the event, call Mastro Auctions at 630-472-1200 or go to www.mastroauctions.com for additional details.
