Gary Cypres isn't just a baseball fan, he's a sports fanatic.
He's a former investment banker who has spent 30 years amassing a wealth of sports memorabilia in a 37,000-foot warehouse near downtown Los Angeles. The collection was estimated to be worth $30 million, when Cypres spoke to CNBC's "Secret Lives of the Super Rich" last year.
It is a museum of treasures — with usually just one visitor.
"Primarily, it is open to me," Cypres told CNBC in 2017. "I come every day."
Though the collection is normally closed to the public, CNBC's "Secret Lives of the Super Rich" got a rare look.
Cypres was first interested in memorabilia from the New York Yankees baseball team and expanded his collecting from there. "I was born in the Bronx, near Yankee stadium," he explained on "Secret Lives of the Super Rich."
But for fans of the Los Angeles Dodgers, who are competing against the Boston Red Sox in the World Series, Cypres's collection is sure to impress.
