Prigov also worked in a genre of so-called Phantom Installations, producing a long undermined series of sketches of installations, which he realised at the first possible opportunity. Untitled (the Transcendental Descend of a Bear) of 1995, was realised at M HKA in 2010. Both the installation sketch and the activation through the realisation of the installation are now part of the M HKA collection.
