Welcome to Fabulous Downtown Las Vegas sign - on Las Vegas Blvd, shortly after entering the city of Las Vegas

The main Welcome to Fabulous Las Vegas sign, along with the majority of the famous Las Vegas "strip", is actually in the unincorporated townships of Winchester and Paradise, Nevada. While almost everyone will refer to Paradise and Winchester as "Las Vegas"... and the correct postal addresses are Las Vegas; the actual boundary to the city of Las Vegas is just north of Sahara Avenue. The "Welcome to Fabulous Downtown Las Vegas" sign is at the intersection of Fourth Ave. and Las Vegas Blvd.
