My wife and I own most of the original C&H books, but my kids want to read them. I know they are going to destroy them, so I'm considering buying the complete volumes for myself and let them have my old books. However, I have read that the complete volume sets don't have some of the additional artwork, poems, etc that the individual books have, which I kind of want to have intact as I am crazy about C&H (even named my son Calvin). Do any of you have these complete sets and know if they contain the artwork and poems from the original books? Thanks!
