I remember seeing those ads in the 60s when I was watching Saturday morning cartoons in our living room in San Bernardino. Annoying as they were to a 10 yo kid at that time, they’ll be missed.
Top Cat was good back then. Mighty Mouse too but more from the 50's that I liked. From age 5 on my parents let me buy all the paper comic books I liked. Why? Because they knew this is how I learned to read.
