SECTION I - CLASS DEFINITION

This class includes means for displaying information by printed or painted cards, calendars, photographic transparency viewers, railroad train station indicators, pictures, labels or tags or index files. Picture frames and stands for supporting pictures are also included. Albums are included in subclasses Changing exhibitors, Hinged leaves; Changing exhibitors, Pivoted plates, and in Picture frames, Mats, Mounts and backs, Pocketed. Such station-indicators as change the reading matter displayed are included under the several subclasses of Changing exhibitors. This class includes in subclasses under the heading, CHECKS, LABELS AND TAGS, CHANGING, READING, devices which select or point out one or more of several inscriptions, characters, or legends by means of a movable pointer. This class includes in the subclasses under CALENDARS means to indicate the date desired by means of pointers. This class includes devices for viewing a picture including a transparency or a series of such pictures or transparencies. Excluded from this class are devices which display a plurality of pictures at such a rate as to create an illusion of motion due to persistence of vision of the observer. Also excluded are devices provided with a double lens so that each eye may view a single picture which differs slightly from the other picture in order to produce a sense of depth, which devices are designated stereoscopes. This class also includes dummy display devices which are provided with means to attract and hold the attention of a viewer, and particularly those which give the impression of falling water and flickering flames.
