The Breakthrough 

"The Breakthrough" is an abstract print by Italian artist Letterio Calapai (1902-1993). The artwork is dominated by a swirl of white lines on a dark blue and green background. The lines are layered, creating an illusion of depth, and appear to depict a sense of movement and energy. The work is a prime example of Calapai's abstract style, which often explored themes of light, space, and the relationship between human and nature.
