We love Dover Publications' Coloring and Activity Books.  They have intricate designs for older kids to color (Victorian House Coloring Book) as well as easier designs for the smaller ones (My First ABC Picture Coloring Book)

I was happy to find sample coloring pages on their website.  As an extra bonus, you can sign up to receive free samples of coloring book pages every week with their Children’s Book Sampler email.  Sign up for the free email here.
