Before display at the MuHKA, and subsequent arrival at Mayor Gallery in London, this work was kept in the suitcase, shown above, and featured in the 2022 film 'De Verdwenen Lijnen van Marlow Moss’ [The lost lines of Marlow Moss] directors: Fifi Visser and André van der Hout – featuring Andreas Oosthoek, Florette Dijkstra, Ankie de Jongh-Vermeulen, Bart De Baere, Yuranan Panya In, Matthijs Erdman, Joost Jobse, Maaike de Wolf-Mol and myself.

This work, Untitled (with blue, yellow and black triangles), is clearly a preparatory study for the canvas with relief White, Blue, Yellow and Black of 1943 – represented in the catalogue in appendix to my 2008 PhD thesis with a black and white photograph, kept in the Tate archives from the collection of Hazel Rank-Broadley, annotated on the verso in Moss’s own hand (P/R35).
