We start out with a mystery. As it says up above, these are the logos of 1949. Wikipedia says the station's first air day was March 27, 1950.
But that was the TV side. The AM side first fired up in 1922.
You know what? I don't care. This isn't a historical site from which you can crib homework essays. It's just a look at post-war radio station logos. They all had one. They had to.
(BTW, you can find a picture of Victor Sholis in studio here, if you wish.)
