60 things to know about the ‘Welcome to Fabulous Las Vegas’ sign Christopher Lawrence, Las Vegas Review-Journal · May 17, 2019 at 10:54 pm It’s one of the few landmarks to be embraced by a city known for blowing its history to smithereens. The “Welcome to Fabulous Las Vegas” sign has survived — thrived even — despite having outlived its usefulness by half a century. That’s how long it’s been since the old Route 91, of which Las Vegas Boulevard was a part, has served as the main corridor from Southern California. The venerable sign, now more likely to greet motorists returning from Town Square or the outlet mall, is 60 years old this month. Probably. Few records exist, and its installation generated no news coverage.
