Reproduction of Umberto Boccioni's sculpture 'Unique Forms of Continuity in Space' ('Forme uniche di continuità nello spazio'), surrounded by the 12 stars of the European Union; on the left the overlapping letters 'R' and 'I'; on the right the letter 'R' and date; on the bottom the engraver's initials 'MAC'.

'Unique Forms of Continuity in Space' (1913) is a bronze Futurist sculpture that depicts a human-like figure apparently in motion. The sculpture has an aerodynamic and fluid form. As a pedestal, two blocks at the feet connect the figure to the ground. The figure is also armless and without a discernibly real face. The form was originally inspired by the sight of a football player moving on to a perfectly weighted pass.

Boccioni's work was in plaster, and was never cast into bronze in his lifetime. His plaster cast is displayed at the Museu de Arte Contemporânea in São Paulo. Two casts were made in 1931, one of which is displayed at the Museum of Modern Art in Manhattan. Two were made in 1949, one of which is displayed at the Metropolitan Museum of Art in New York and other one at the Museum of Twentieth Century in Milan. Two more were made in 1972, one of which is displayed at the Tate Modern in London. Another eight, in 1972, were made not from the plaster, but from one of the 1949 bronzes. One bronze cast is in the Kröller-Müller Museum in Otterlo, Netherlands.

A geographical map of Western Europe spans the outer ring and inner core on the left side of the coin.

12 stars are located on the left side of the outer ring, with six stars atop the map of Europe and six stars below it; six vertical stripes cut across the inner core of the coin, visually connecting the upper and lower star segments.

Luc Luycx, a designer at the Royal Belgian Mint, designed the Euro’s common reverse; his initials, LL, are seen on the right side of the design, just under the “0” in “20.”
