About the Work

The sky, the sea, the universe: these are usually our first associations. Yves Klein declared this intense blue his ‘trademark’ and had it registered. Yet he made no claim to the individual application of the paint. The work was created in the founding year of the Nouveaux Réalistes. A typical feature of their works is the involvement of ordinary, everyday objects. The sponges and gravel used here look like extremely enlarged grains of pigment. Klein deliberately omitted the confining frame, thus suggesting that his composition can continue infinitely in all directions.

Research and Discussion


Object History
Yves Klein
Georges Marci, Gstaad, ca. 1960
Slg. Boutard, Zürich
Galerie Zwirner, Köln
verkauft an die Städtische Galerie, Frankfurt am Main, 1981.


Since 2001, the Städel Museum has systematically been researching the provenance of all objects that were acquired during the National Socialist period, or that changed owners or could have changed owners during those years. The basis for this research is the “Washington Declaration”, also known as the “Washington Conference Principles”, formulated at the 1998 “Conference on Holocaust-Era Assets” and the subsequent “Joint Declaration”.

The provenance information is based on the sources researched at the time they were published digitally. However, this information can change at any time when new sources are discovered. Provenance research is therefore a continuous process and one that is updated at regular intervals.

Ideally, the provenance information documents an object’s origins from the time it was created until the date when it found its way into the collection. It contains the following details, provided they are known:

  • the type of acquisition and/or the way the object changed hands
  • the owner's name and place of residence
  • the date on which it changed hands

The successive ownership records are separated from each other by a semicolon.

Gaps in the record of a provenance are indicated by the placeholder “…”. Unsupported information is listed in square brackets.
