LETTSWORTH — A highway marker unveiled six months ago to honor blues singer-guitarist Buddy Guy has gone missing after being knocked down by a car last month and the Pointe Coupee Parish Tourist Commission wants the marker back.

The marker belongs to the commission. In a statement on Wednesday, Executive Director Jeanie Andre urged the person or persons who took the sign or who know anything about it to help the commission recover the sign. "If you wish, you may remain anonymous."

The sign, measuring about 3 feet by 4 feet and standing 5 feet off the ground on a sturdy post cemented into place on La. 1 in the community of Lettsworth, was unveiled on Dec. 8, 2018. It marks the spot where an album cover was shot. A separate marker noting his inclusion on the Mississippi Blues Trail still stands on La. 418.

Guy, who's in his 80s, grew up in a family of sharecroppers in Pointe Coupee. He's an eight-time Grammy Award winner and winner of the Grammy Lifetime Achievement Award. 

Now on tour throughout the central and northeastern U.S., with a show Thursday in Rochester Hills, Michigan, Guy had been on hand for the unveiling last December, along with family, friends and fellow musicians, and local and state officials from Louisiana and Mississippi. 

"I thought playing in the White House was my favorite thing, but I think coming home is the best," Guy, a native of Lettsworth, said at the ceremony. 

State highway 418, where it runs through Lettsworth, has also been renamed Buddy Guy Way, approved by the state legislature last year in a bill authored by then state Rep. Major Thibaut, now Pointe Coupee Parish president. 

Andre, with the tourist commission, said that on May 11, a car went off La. 1, knocking down the historical sign's post and breaking the sign off at the mounting bracket.

The marker was seen on the ground the day of the accident, but disappeared in the days following, Andre said. The matter has been investigated by the Sheriff's Office, she said.  

"Our organization would like it returned," she said.

The story has been corrected to note that the missing marker was erected along La. 1 and that the Mississippi Blues Trail marker is still standing.
