Kate Greenaway’s Book of Games (1889)

A book about children’s pastimes and games with rules for playing. It includes games like I Love my Love with an “A”, Blind Man’s Buff, Frog in the Middle, Russian Scandal (this is an old name for the Game of Telephone, before the invention of the telephone became really popular – I don’t know why it’s specifically Russian, but I’ve also heard it as Russian Gossip or just Gossip) and Twenty Questions. Some games are like playground games (some of them are even still played on playgrounds today), that require running and motions, and others are more talking games (some of those have become classic road trip games, played in the car). Pastimes include making soap bubbles, flying kites, and swings. One of the interesting things about this book, besides noticing which games are still played and which are more obscure now, is that the children in the pictures are actually wearing clothes that are from an earlier part of the 19th century than when the book was written. This is a classic feature of Kate Greenaway’s illustrations, also seen in her other books. By Kate Greenaway.
