This is next in the series of adult grayscale coloring book series featuring retouched images from public domain sources and Dr. T's personal collection. They can be colored with your choice of colored pencil, crayon, pastels, or gel pens just to name a few. Grayscale coloring is different from line drawing coloring in that you utilize the existing shadows to help enhance the colored page.
Book features:
60 unique images to color
Each picture is 8x10
Pages are printed one-sided to prevent bleed through to next page (if using markers use a sheet between the pages).
Printed on pure white #60 paper
Grayscaled to just the right tone so the page isn't too dark to color but not so light to lose detail.
