BTW My mother supplied the sound effects when she read books to us.
At least until we got our own library card (3rd grade). From then on, it was up to my imagination to fill in the effects.
I blew through the 'Juvenile' section in 2 years and had to get permission to read from the YA section.
We had TV (Annette Flunecello was a new Mouseketeer).
Imagination was not limited to Black and White
