Multiple by Ilya Kabakov produced by Ronald Feldman Fine Arts as their [1988] holiday project sent to friends and artworld colleagues. "Whose Fly is this?" "I don't Know," is comprised of a plastic black-fly housed in a clear acrylic box with a small paper colophon on the bottom of the box. The colophon says "Whose fly is this?" and that it is "From the 1988 Untalented Artist's Exhibition in the Communal Kitchen." Colophon is signed and numbered in pencil by the artist.
