ABSTRACT:
An apparatus is provided for displaying a visual exhibit. The apparatus includes a display unit for housing an exhibit and a chamber unit for housing the display unit. The display unit includes a transparent envelope having a proximal portion configured to form an opening for receiving the exhibit and a distal portion to cover and protect the exhibit. The chamber unit includes a transparent, expandable compartment defined by an outer wall. The wall is formed to include an aperture for permitting the exhibit to be inserted into the display unit from outside the chamber unit. The aperture is coupled to the proximal portion of the display unit to suspend the display unit inside the chamber unit. An inflator extends through the wall of the compartment for filling the compartment with a gas. The inflator is coupled to the display unit to orient the display unit in a predetermined relation inside the chamber unit.
