The collection started with the original dress that Judy Garland wore in "The Wizard of Oz," until a new director changed it.
"He revamped Judy Garland, got rid of the blond wig and upgraded the fabric," Barry Barsamian said.
But with this, Barry was hooked, and he had to have part of Hollywood history.
Among the things in Barry's collection are Shirley Temple dolls from the 30s, Judy Garland's ring, a Phyllis Diller gown.
"Phyllis Diller's famous chandelier dress is one-of-a-kind. It was designed by Omar of Omaha," he said.
And a Donna Karan original for Barbra Streisand.
Barry has been collecting Hollywood memorabilia for more than 30 years. But much of it has been in storage at home in Oakland or in a warehouse. He's still collecting.
"You meet people at collectors' shows; you meet people in the industry," he said.
Friends give him things. His cousin gave him Mike Connors' jacket from "Mannix" and Jane Russell gave him a ring. The items he buys come with a letter of authentication.
The exhibit will be on display for at least three months. But would he ever sell any of it?
"Am I ever going to get rid of it? Maybe someday, not now," Barry said. "I suppose I am a Hollywood historian. I like to preserve and protect the idea there's history here."
