Abstract
For advertising or amusement purposes, a hand-held stereoscopic viewer is provided with a cavity into which a container may be inserted and removed. The cavity is located adjacent the nostrils of a user of the viewer and is separated from the other portions of the viewer and is capable of being enclosed. The container carries an odor-producing substance which may be a solid or a gel or a liquid absorbed into a suitable material. The container has a replaceable seal and when sealed inhibits odor essences escaping before or between uses. In use, the seal is removed from the container and it is inserted into the cavity. As the odor is produced, it reaches the atmosphere adjacent the nostrils of a user of the stereo viewer through odor-passage holes positioned between said odor-producing substance and the nostrils. These odor-passage holes can be positioned in the container or in a lid covering the enclosed cavity in or on the viewer. Scenes viewed in the stereo viewer can be compatible or associated with the odor provided and dispensed.
