For those who like a bit of dark humor, but gently done, and in small doses, leavened by much old-fashined fun, there is Father Fox's Pennyrhymes, by Clayde Watson, illustrated by Wendy Watson (1971). It's kind of a twisted mother goose enacted by dressed-up rural Vermont foxes, who give voice to many snarky, humoerous, and even sweet asides in the pictures (so I can't really do it justice).
Here's an example of one of the "darker" rhymes:
Little Martha piggy-wig
Run away and dance a jig!
If you weren't so fat and sweet
You wouldn't be so good to eat.
The picture shows little Martha, the only pig on the fox-covered playground, jumproping for dear life (literally).
Poking around on line, I see that I am not make a new and earthshaking discovery here. Oh well. It just got a huge blast of publicity back in January,here at Read Roger, and Sam Riddleburger looked at it in some detail last September here, and doubtless there are many others. But I am the first, as far as I know, to feature little Martha.
I shall eagerly look for Father Fox's Christmas Rhymes when it becomes seasonally appropriate to do so.
