I can't find them again and I have tried. It was these little books with black and white art and it was of classic novels, Frankenstein, etc. I can still see some of the images when I think of the books. It inspired a love in me for those stories that has lasted a lifetime.
My Mom was a special ed teacher and they were in her classroom as a set. I would go read them after school. Google Gemini suggested Classics Illustrated but I don't think that is it. These were black and white and cheaper than that. Something a teacher would have in their classroom.
Edit: Upon chiding Google Gemini and reminding it that it was black and white I think it found it!
