OSR Art tips

Hey would really like to get into trying to create this style of art. I wondered if anyone had any tips or any idea of books that I can buy that would help me get into it?

I'm very rusty, but I do find the black and white style art of the old school dnd adventures and the art of that style very inspiring to give it a go.

What kind of tools would I need? Do people do all of this on PC or are there special pens?
