Our Walrus and Carpenter Wonderland Wall Clock runs backwards and features the 1871 Through the Looking Glass illustrations. It keeps perfect time in reverse and you can watch the second hand go counterclockwise! Easy to read in a mirror and keeps perfect time in reverse. It is a full 1/4 inch thick and runs on a standard size AA battery. The clock comes wrapped and layered in Alice in Wonderland wrapping paper and layered protective foam for the hands. We have sold thousands of these to individuals over the last 28 years and the customers love the beauty and longevity of our clock faces.
