My coloring books have 24 pieces of art in them to color. Some of the art is contained within the associated books. Some of the art is from my buttons, magnets, or note cards. And some art is only available as part of the coloring books. At the end of the coloring book there is a list showing which characters they are, the countries they live in, or a mixture of both.
These are also available for purchase through Lulu and at select stores that carry my books.
