At least your mom gave yours away, mine just tossed them in the trash ... were comics from the 30s which I bought ($0.01-0.05 each) at the annual rummage sales in the late 40s and early 50s.
That’s heartbreaking. I’m assuming mother gave them away. I can’t remember now what she said when I looked for them and they were gone.
Mother SHOULD have loved them. She was a fine arts major at U of Chicago and she taught me to draw art deco in the black Chicago dirt by smoothing it and drawing just a few lines to make me mentally fill in the rest. When I got to U of Chicago and studied in the same studio, the teacher had us draw a nude upside down. So I guess mental games with art was the thing there. But somehow comics weren’t art to her, where they are to me.
