Abstract
Abstract A panel mounted display device having a unitary molded casing whose exterior and interior sidewalls define a plurality of compartments and whose rear wall contains access apertures. The sidewalls of each compartment have a lower portion terminating abruptly into an upper recessed portion. Indicia bearing disks are seated on the flange surfaces thus formed and are rigidly retained by integral protrusions extending into the compartments from the upper portions of the sidewalls. The upper portions of the sidewalls form shields about the individual compartments.
