Cost around $1400 or figuring the average yearly wage in 1948 of $2950 you had to work 6 months to pay for that car.

What the sun visor did for aerodynamics, those chrome shields (in the color photo) covering the upper half of the headlights did for seeing where the heck you were going at night. But they too added coolnicity. That amber Indian face on the Pontiac hood (viz., Chief Pontiac) lit up. In the middle of the last century when I wrecked both of my parents' cars in six days, one was a 1942 Buick sportin' one of those visors. I think even that was totaled.

They were a not-uncommon accessory back in the 40s and 50s. I'm not sure whether most people who got them did so for practical purposes or just to make their cars look cool, sort of like rear fender skirts. They sure didn't do anything for the aerodynamics. But coolness:

Is that a sun-visor or something?
