Children's Poem on a Postcard

I'm hoping to do a wide variety of swaps here on the Hundred Acre Wood, so here's a simple, low-cost postcard swap. Take a postcard, write your favorite children's poem on the back, pop it in the mail, and you're done! Examples of children's poets include Robert Louis Stevenson, Christina Rossetti, Edward Lear, Shel Silverstein, Lewis Carroll, Ogden Nash, A.A. Milne, and so on. But of course, you may also choose a child-like poem that was not necessarily written for kids (such as e.e. cummings). Postcard image is not required to match subject matter, but it might be fun to try to find a matching postcard if you'd like!
