Claim:
A display comprising: a frame member defining a pair of windows, a carrying member including two image bearing parts, the carrying member being movable relative to the frame member such that each of said images can be moved past a respective one of the windows to be visible therethrough, and a pair of shield members for the windows respectively, the shield members being arranged such that if the respective image bearing part is moved past the respective window in one direction the image passes between the shield member and the window and can be seen through the window, but if the respective image bearing part is moved past the respective window in an opposite direction the image passes on the opposite side of the respective shield member and is thus obscured by the respective shield member and cannot be seen through the respective window, the arrangement being configured such that when moving in a first direction one of the image bearing parts passes between the respective shield member and window to be visible, and the other image bearing part is obscured by the respective shield member, and when moving in the opposite direction said one image bearing part is obscured by the respective shield member, and the other image bearing part passes between the respective shield member and window to be visible.
