The pencil drawing by Hammershøi does not have a title nor an exact date. An estimate is that he made it in 1880, when he was 16 years old. The drawing may depict an ice block or cube, a new object in domestic households at the time. The Hirschsprung Collection, from which the work is borrowed, has given it a title for archival purposes; Transparent cube on dark background.
Vilhelm Hammershøi (15 May 1864 – 13 February 1916), was a Danish painter.
