Lyon Estates Sign - Random Thought
With the way that the Lyon Estates signs were just sitting in front of the curb instead of being permanently built into the lawns of the corner lots (as is done in most housing developments) it had me thinking about how these were probably temporary signs became permanent the same way that the "Hollywood" sign did.
The Hollywood sign was meant to be a temporary advertisement built by the developer which eventually became a landmark. So when I see the Lyon Estates signs just sitting out in the middle of the street (primarily because it's a movie prop) it had me thinking that if this was IRL, the developer would have taken them away sometime during the 1960's when the construction was fully complete. But somehow they became permanent as the bases of these signs got buried in several layers of asphalt with each course of road maintenance.
