The exhibition of Arnold Gross was opened in 1999 in the Applied Art Museum. The exhibition represents both the (painter and graphic) artist and the collector. The diorama entitled Applied Art Museum was arranged in connection to this exhibition. On the diorama we can see three colour prints of the main facade of the building, with the "belle époque" miniature figures in the front.

Our exhibition at this time displays such rarities which previously had not been seen or are less known. Plates and prints are placed beside one another, and in some cases variations of the same graphic works set different atmosphere. The mixture pages printed from several plates are also interesting.

The graphic artist is a collector as well. He collects a good number of relics, toys, miniature objects, trains, rocks and minerals. An exhibition of these items is also arranged (recalling the atmosphere of the toys and small trains models of old days, and demonstrating the world of unique minerals). These objects tend to occour in his pictures (train, railway, etc.) Glittering colours and tones ornament his mild engravings works, recalling the marvellous colours of the minerals in the artist’s collection.

That is how the collection and the artworks are connected. This world is made up by toys, railways, minerals and graphic works. The latest coloured engraving of the master (entitled: Encyclopedia) sums up the life work and arc poetica of the master.

The title of the exhibition is "The toys of nature". It expresses the master's clinging to nature. From the time of his early works he had been inspired by the landscape and his motherland, the region of Torda. His landscapes are characterized by playfulness. Gross always kept in his soul a love of nature, a childlike playful imagination and independent ideology.
