Untitled (Hommage á Santomaso) 

This untitled work by Italian artist Enrico Castellani is a prime example of his signature "surface" style. The minimalist, white canvas features an array of small, evenly spaced indentations that create a subtle interplay of light and shadow, emphasizing the textured surface. Castellani's work, often referred to as "concrete art" or "spatialism," explores the physicality of the canvas itself. This piece, likely from the late 1950s or early 1960s, reflects Castellani's exploration of abstract form and the tactile quality of the art object.
