And while I know many of you aren't New Yorkers, and maybe do or don't have this kind of diversity in your cities and towns, I can't recommend this book enough as a simple marker for children. It is an amazing tool that moves me on the topic of being open, while accepting simple and wonderful commonalities children have with other children around the world (and maybe right where they live).
Here's the original, which was out of print for years. The re-print is vibrant and gorgeous.
