A hermetic enclosure assembly, having utility for preservational storage and/or display of objects susceptible to degradation by exposure conditions such as ultraviolet radiation, visible light, oxygen, humidity, microbial, fungal, and insect species, internal acidity and external acidic gases, and the like. The enclosure assembly includes a gas-impervious housing, a mounting base, and a back cover plate, with an oxygen indicating means in communication with an interior volume of the enclosure assembly, and a slow vapor-released deacidification medium being arranged for dispersing deacidification medium vapor into the interior volume of the enclosure assembly. Also disclosed is an appertaining method of preservationally and protectively enclosing an object for storage and/or display. The invention has particular utility in the storage and/or display of cellulosic objects, which are especially susceptible to embrittlement and decay at low pH conditions, in exposure to visible light, oxygen, and moisture.

A method of preservationally and protectively enclosing an object for storage and/or display, comprising the steps of: (I) providing unassembled enclosure components comprising: (a) a gas-impervious housing including a transparent front panel for viewing of an enclosed object, and side walls extending (i) rearwardly from the front panel and (ii) continuously about the perimeter of the front panel, the side walls at their rearward portions being interiorly recessed to accommodate flush-mounting of a back cover plate at the rearmost extremity of the side walls; (b) a mounting base having a front main surface for mounting of the object thereon and a rear main surface, said mounting base permitting gas communication with an interior volume of the enclosure assembly bounded by the front panel, the front main surface of the mounting base, and associated portions of the side walls, with the mounting base being of a size and shape to fit interiorly of the housing; (c) a back cover plate flush-mountably engageable with the interior recess portion of the side walls, having first and second ports therein, and having selectively openable input and output valves therein for ingress of gas into the interior volume of the enclosure assembly and egress of gas therefrom, respectively; (d) means for securing the mounting base in the interior volume; (e) means for hermetically sealing the rearward portions of the side walls to the flush-mounted back cover plate; (f) means for visually indicating the presence of oxygen in the interior volume of the enclosure assembly, disposed in the first port of the back cover plate; and (g) a vapor-release deacidification medium disposed in the second port of the back cover plate and arranged for dispersing deacidification medium vapor into the interior volume of the enclosure assembly; (II) mounting the object on the front main surface of the mounting base; (III) assembling the components (a)-(g) to form the enclosure assembly; (IV) opening the input and output valves in the back cover plate; (V) mixing an inert gas with a vapor-phase deacidification component to form a multicomponent fill gas mixture; (VI) flowing the multicomponent fill gas mixture through the input valve into the enclosure assembly to displace air and moisture therefrom through the output valve, for purging of the interior volume of the enclosure assembly; and (VII) closing the input and output valves.
