Listen, Listen has beautiful illustrations and just the right amount of text on each page to keep a toddler interested.
I love this one - Zig Zag Zebra - containing fun art projects for your preschoolers.
There's even a decent Spanish selection. (I am going to have a trilingual nephew pretty soon!) Here are a couple: Juan y los frijoles mágicos (Jack and the Beanstalk) or Cerdota grandota (How big is a pig?)
For older kids, there are lots of books that celebrate and teach about other cultures. Here's one about Peru called "Up and Down the Andes".
