A Queens man claims a sports company turned his treasured Yankee memorabilia into a plain old memory.

Edward Kull entrusted Steiner Sports with a “one-of-a-kind” 1961 World Series jacket autographed by nearly 40 Yankees legends, but the garment was stolen in an apparent inside job, a lawsuit charges.

The lawsuit says that several Steiner employees were fired, but the jacket — signed by stars such as Derek Jeter, Joe DiMaggio, Mickey Mantle, and Reggie Jackson — has disappeared.

“It’s hard to imagine that I’ll ever see the jacket again,” said Edward Kull, 28, a sports marketer for The Coca-Cola Company.

Three generations of the Kull family had gotten Bronx Bombers stars to sign the jacket, starting with Kull’s grandfather, Genaro Calabrese, who was given the jacket by Jack Reed, a friend who played for the 1961 Yankees.

Steiner Sports said their insurance company was looking into the matter.
