I hope you enjoy coloring the 26 penguins representing various careers in this coloring book. You will find a variety of different penguins in various careers from the Hula Dancer to The Wino. You can use any type of medium to color these pictures. I do caution that if you use markers that you put a couple of blank pages under it as there is potential for them to bleed through to the picture on the next page. I have more ideas for coloring books in many categories. I am also creating coloring books for left handed colorists.
