An important work in the exhibition dedicated to Johan Thorn Prikker is the study The Harbour Company from 1917. It is a design for a mural in the Town Hall of Rotterdam; it was rejected because it was considered too modern. The enormous canvas measuring 425 x 351 cm was stored in the depositary on the Metaalhof, where in was rolled up on a far too small wooden roll and placed on the floor - an example of the overdue maintenance in the depositaries. When it was unrolled, the canvas was found to be considerably deformed. The edges were damaged; there were small tears in it. At the place where sharp creases had been made at the bottom of the canvas, the paint layer had peeled off. The flat paint was peeling away here and there and there was a grey layer of dirt. If the work was to be exhibited, it would have to be restored. The work was carried out by the Stichting Restauratieatelier Limburg [Restoration Studio Limburg Foundation] (SRAL) under the supervision of Jos van Och. It was also important, after the restoration and exhibition, that the storage facilities were improved, including storing it on a roll with a larger diameter. Under the supervision of the external restorer, the painting was mounted flat against the wall of the gallery on the doubled over edge that was applied to strengthen the edges. Although during the work conservation was the prime concern, the removal of the surface dirt and the minimal retouching of the damages meant that the strength and clarity of the illustration were much better expressed.
