The welcome sign's design, which doesn't have a copyright owner, has become a fixture in travel. In 2009, the sign was added to the National Register of Historic Places.

Betty Willis worked as a commercial artist in Los Angeles before returning to Las Vegas, where she worked for sign companies and designed the famous diamond-shaped beacon of flashing lights.

Willis also designed neon signs for the Moulin Rouge casino and Blue Angel motel in Las Vegas.
