Filled with original, hand-drawn illustrations of celebrations, these Mindware® adult coloring books incorporate the color-by-number concept. Coloring books for adults help lower stress. Coloring books are also wonderful activities for seniors. As you color, fantastic hidden images reveal themselves. Once you've completed the numbered designs, try the un-numbered version of the illustration to add your own unique style. Each design, printed on artist-quality paper, creates a frame-worthy finished product! Includes 23 perforated pages including 8 fold-out pages that extend to a 10" x 15" size.
