Brutalist artwork

Impressive piece of brutalist wall art, made in Belgium by an unknown artist in the 1970s. This type of reliefs in copper or bronze was particularly produced in the 1960s and 1970s. In this case, it is made of copper, worked from a relatively thin sheet, hammered or pressed. If you turn this work over, you can see that the mirror shapes on the back are hollow. The artist pushed and stretched the metal outward from the back to create three-dimensional shapes and relief patterns. This technique is known as "repoussé, " for which copper was a preferred material. The greenish effect on the deepest parts is called "verdigris" or copper patina. Sunlight further enhances these colors. One of the upper corners has been bent, otherwise in good condition.
