Marty Stuart and his country legend wife Connie Smith donated part of their massive country memorabilia collection to the Country Music Hall of Fame Wednesday.

Several pieces, including the late Lester Flatts’ guitar were personal, were very personal.

Flatts was Stuart’s mentor and hero.

The donation is so significant that Flatts' old duo partner, Earl Scruggs, came by for the ceremony.

The guitar was one of dozens that Stuart and Smith made to the Country Music Hall of Fame.

Music Row has known Stuart has been collecting country memorabilia since he was a boy growing up in Philadelphia, Mississippi.

"I personally know how much he loves some of these things,” said Smith. “I think a gift is really when you give something that you love and that you treasure."

Smith donated the first-ever acetate copy of her break-out hit "Once a Day".

The donations also included items from others, including Hank Williams, Johnny Cash and Merle Haggard.

Hundreds of thousands of fans will enjoy them in the future.
