The woman who came up with a neon sign that has welcomed countless visitors to "fabulous Las Vegas" since 1959 has died.
Betty Willis, credited with designing the "Welcome to Fabulous Las Vegas" sign, died in her Overton, Nevada, home on Monday, according to an obituary on the Virgin Valley & Moapa Valley Mortuaries website.
The 91-year-old artist's sign sits in a median in the middle of Las Vegas Boulevard south of the Strip.
"It's the most recognisable icon in the world," said Danielle Kelly, executive director of The Neon Museum in Las Vegas, where the signs of Sin City's past are retired.
In 2009, the sign was added to the National Register of Historic Places.
Willis, born in 1923 in Overton northeast of Las Vegas, worked as a commercial artist in Los Angeles before returning to Las Vegas, where she designed the diamond-shaped beacon of flashing lights.
