The Kingfisher Playtime Treasury

 Selected by Pie Corbett

This is a pretty good collection of children's rhymes, skipping rhymes, schoolyard games and the like.  They're appropriate for children a minimum of three years old.  There's lots of variety and they're organized by category.  A lot of heavily gendered rhymes about kissing boys and getting married, but that's because they're traditional. Some of the wording is not what I'm used to.

I'm planning on using it for upcoming birthday parties.

 The art looks like it's stolen from Janet Ahlberg.  They included Each Peach Pear Plum, though they use different lines.

And they seem to have a Jolly Postman, too.

Really weird.  But I guess Janet is dead now, so it's fair game?
