So it was about 1952 and my parents had this old floor standing console radio with a 15 inch speaker well before we owned a black and white television. I was 6 and the radio had this green pulsating thing on it. I loved playing with it. I was so fascinated by it, twisting the tuning knob back and forth, watching this green thing enlarge and shrink. Kept me entertained.
It looked kinda like this, except no hood on the top.
Would like to find a color set with a magic eye.
