Totally Vintage has these 15 Mr. Men Books for sale. Oh my, I had forgotten these books, but I loved them when I was little. I loved the drawings. Just simple shapes made into characters. Maybe it is because I never learned to draw anything more complicated than basic shapes.
I have never come across these gems in my treasure hunts. I want one just to read it one. I specifically remember Mr. Noisy.
Did you ever read them?
