Despite their age, many of these books are still extremely readable even by young readers. I thumbed through Frog: the horse that couldn’t be tamed and really enjoyed it. The hand-drawn pictures in the book are also very readable and cool in a retro way. Makes me sad about the current quality of our children’s literature.
This may be because there is so much low quality stuff everywhere while only the good and high quality ones survived from the past (Survival of the fittest I guess). So the past looks like it was all good but the present is mostly rubbish.
