Through a contractually defined agreement between the artist and art collector Jochen Kienzle, the artist was permitted 20 minutes unsupervised, unsurveilled, and alone in the collector’s home. The contract stated that during this time Schwebel would remove a single item from the home. The identity of this extracted object is to remain a secret, concealed from both the collector and public knowledge. The extracted object taken from the collector's home introduces an absence that persists so long as the object remains unknown to the collector. The Kienzle art collection also acquires this intervention, in the form of an unspecifiable lack, as an artwork within its holdings.
