Abstract
Abstract A display device for changeable signs having a transparent cover for receiving therein in upright position the changeable cards carrying suitable indicia. The cover is enclosed on all sides except the bottom, where it receives a bracket and which substantially fits in the opening to seal the latter against the entrance of foreign substances. The cover is frameless and formed of relatively thin walls which overlap the bracket at the bottom. Ears are formed on the opposite end walls at the bottom extending substantially throughout the width of the cover and in position to be seated upon the bracket. The ears are internally threaded to receive fastening screws detachably connecting the cover with the bracket and which can be inserted through openings in the bracket into the threaded openings in the ears.
