Does anyone remember these books from their youth? They were published in the mid 70s and mostly found within schools. My primary school still had them in the late 80s, but I've never seen any since. You can get them on Ebay/Amazon, but they're like £20 per book and they're only 30 pages each!
Anyway, I just wondered if anyone else read these whilst at school. They had a magical, creepy vibe to them and I always recall the illustrations being rather creepy.
