Carel Visser is seen as one of the most important constructivist sculptors of the Netherlands. His later work is characterized by the assembly of a variety of materials, such as tires, oil drums, car windows, leather, sheepskin, eggs and so on. He made organized connections, a kind of assemblages, with this so-called great and sometimes small objets trouvés (found objects). Some of his work has been compared to a musical composition in which repetition and variation play an important role.
Around 1960, Visser was focussed on massive closed cube of iron and "slack" cube wire. Visser, among other things, was inspired by nature (plants and animals) which also explains his use of natural materials such as wood, wool, sand, feathers, bones, rope and leather.His works from the period 1975-1985 could be called environments, as opposed to the more sculptural work as the dying horse (about 1949).Wikipedia
