HALLOWEEN COLORING BOOK.The best QUALITY materials used in the production of the book! No truly scary or unnecessary gory Halloween photos which I do not agree with and would never allow. That's not what Halloween (Samhain) is about anyhow. Crayons and colored pencils would be best to use as opposed to markers that bleed thru. All pictures/graphics done by myself. Never any stock photos in my books! Large 8.5" x 11" pages.
