Inside the Crayola Experience store you can fill up a box with all of the crayons and markers you want. This image is a small part of the marker display. I did not have a wide-angle lens and could not step far enough back to capture the entire wall. Crayola makes a LOT of different colored markers.
When I stare at this image, my eyes start to go crazy!
