SPIRAL EXPANSION OF MUSCLES IN MOTION
Sculpted in 1913, final exhibition in the 1916-17 posthumous Grande esposizione Boccioni in Milan, destroyed in 1927 in Acquabella, Milan.
New photo discovered
During the final stages of reconstructing Spiral Expansion of Muscles in Motion we discovered an image that, to our knowledge, has not yet been acknowledged to include this sculpture. This image was published in the newspaper Il Secolo Illustrato in January 1917 (1).
F. T. Marinetti is shown standing next to Unique Forms of Continuity in Space, but what is especially interesting is the top right image on the page. It could be mistaken to show the same sculpture, but closer scrutiny reveals it to be Spiral Expansion of Muscles in Motion (2, and the reconstruction, 3). This provided us with valuable information since there are only photographs from four other angles of this sculpture (4).

UPDATE
One of the photographs used for the Spiral Expansion of Muscles in Motion reconstruction was very graciously made available in much higher quality by the MAC USP Archive in Saõ Paulo (donated to them by Zeno Birolli). Details of the left side of the head are more clearly visible here, which enables better reconstructive solutions than earlier. Things suddenly fall into place in a way that makes perfect sense (5). Considering this, an updated 3D revision is underway, and a full-scale version will be 3D printed in 2022.
