Her name was “Lucille,” and in B.B. King’s hands she gave voice to the “King of the Blues.”

Julien’s Auctions announced Tuesday that King’s black Gibson ES-345 prototype guitar is among the items from his estate that will go up for bid on Sept. 21.

Julien’s says Gibson gave King the instrument for his 80th birthday. The headstock has “B.B. King 80” and a crown inlaid with mother-of-pearl. The guitar is estimated to be worth $80,000 to $100,000.

THE THRILL IS GONE: BLUES LEGEND B.B. KING DEAD AT 89

The guitar was not the first to bear the name. The story goes that King first used that moniker for a guitar he rescued from a fire while he was playing an Arkansas club in 1949. The blaze broke out as two men fought over a woman, and the musician narrowly escaped death after he went back into the club to save his guitar, the auction house said.

B.B. KING'S DAUGHTERS CLAIM HE WAS POISONED

When King learned the woman’s name was Lucille, he named his guitar after her “to remind himself to never fight over a woman or run into a burning building,” the auction house said.

The National Medal of Arts that President George H.W. Bush presented to King in 1990 is also up for auction. So are his touring van, jewelry and clothing.
