Could Maybelle Carter's Gibson L-5 guitar be returning to the Country Music Hall of Fame and Museum? Signs seem to be pointing that way following Thursday's (Aug. 19) announcement of a press conference at the museum. As Carter's primary guitar on most of the Carter Family's earliest recordings, it is regarded as "the most important single guitar in the entire history of country music," according to George Gruhn, an internationally recognized authority on musical instruments. The guitar, built in 1928, had been on loan to the museum since 1998 but was reclaimed by its current owner in May and consigned to Gruhn's Nashville guitar shop for an asking price of $575,000. Details on the future ownership of the guitar are expected to be revealed Monday (Aug. 23) during the press conference at the Hall of Fame. Among those scheduled to attend the event are Country Music Foundation board president Vince Gill, Hall of Fame member Earl Scruggs, Randy Scruggs, Marty Stuart and the Whites. Also in attendance will be record producer John Carter Cash, son of Johnny and June Carter Cash and the grandson of Maybelle Carter.
