Possibly the most inappropriate children’s book ever devised. From 1974. As well as the innocuous stuff about throwing parties and baking biscuits (which I’ve left out) it shows you how to magic warts, how to make a cursing potato figure to stick pins in, how to plant flowers in honour of the moon goddess, and more… including a ritual to summon spirits, complete with cut-out cardboard pentagrams.
You’d never get away with this nowadays. Frankly I’m not sure how they got away with it back then.
