Abstract: Among other things, the present invention provides a device for attachment to a garment. A base member of the device has a planar top surface portion which is slidably engagable with a planar bottom surface of a support frame, upon parallel movement of the base member in a first slide direction relative to the support frame. An internal chamber is defined within the support frame and a display panel is slidably insertable into same through one or more edge openings. Retainment means retain the top surface portion and bottom surface portion in intimate contacted relation with each other during the parallel movement. Cooperating portions of a catchment means engage each other to hold the support frame against parallel movement opposite the first slide direction once a display configuration is reached. An attachment means removably secures the device to the garment.
