ABSTRACT:
A display case for supporting and viewing of a museum piece, the case including a base providing a lower chamber for a humidity buffer and a transparent cover providing an upper chamber for the piece on display. The case is substantially airtight, with sealed access ports in the base for inserting and removing humidity buffer containers, and with a clamped soft seal between the cover and base for removal of the cover to provide access to the display space. In the preferred embodiment, the humidity buffer is contained in cylindrical containers which rest on a sloping shelf in the base for ease of handling, and the lower and upper chambers are separated by a platform which provides a restricted airflow path between the chambers so that opening an access port does not result in substantial airflow into or out of the upper chamber.
