This oddity was published by Virgin/Mastertronic in Europe in the early 1990s, about the same time as their individual Infocom Mastertronic packages. Like the Infocom release, it contains the original three Zork games in a single package. Not a very effective use of the new (at the time) CD-ROM medium. The box contains the CD and jewel case with inlay, three manuals from each of the small black Mastertronic boxes, and a glossy B&W of the Zork I map, with the game title added at the top. The logo reads "Infocom from Tronix", rather than Mastertronic.
The box has the same layout and dimensions as Virgin's Infocom Collection.
