Abstract: A display device comprises a rotary carrier and a plurality of supports for respective display slats which supports are mounted on the carrier for rotation around the axis of rotation of the carrier and for rotation about respective axes, which are equiangularly spaced about the axis of rotation of the carrier. A slat is mounted on each support with its longitudinal center line coaxial with the axis of rotation of the support. The arrangement permits each slat to be turned to show both its faces and by movement of the slats around the axis of the carrier it permits alternative slats to be brought into the display surface.
