Abstract: An adjustable glass display case, which permits ready assembly and disassembly, is provided which includes a frame having four glass plates, a generally horizontally-disposed top plate, a generally horizontally-disposed base plate and two upstanding, spaced-apart side plates disposed generally between the top and bottom plates. Each of the glass plates has two longitudinally-extending, spaced-apart rows of holes formed therethrough and is detachably secured to the other plates of the frame adjacent thereto. The case also includes a back glass plate disposed adjacent to, and detachably secured to the frame. In addition, at least one vertical glass divider is positioned between and disposed generally parallel to said side plates and is detachably secured to the top plate and bottom plate by a clamping assembly which is at least partially retained within at least one of the holes of the top and bottom plates.
