Collage Op Art Ảo Giác Mid-Century

Experimental mid-century modern graphic collage on warm off-white paper. Asymmetric composition featuring [a cropped black-and-white profile portrait] on the right side, rendered in coarse halftone and ink textures, partially obscured by a large black semicircular hair shape filled with dense dots and scratchy brush marks. From the center, a hypnotic black-and-white checkerboard vortex spirals outward, colliding with overlapping organic blobs in [saturated primary colors: cobalt blue, vermilion red, lemon yellow, lime green, pale pink, gray, and cream]. The background consists of precise black grids, vertical stripes, dot screens, and technical line patterns, interrupted by a tall red striped column. 1960s–1970s experimental editorial design, psychedelic Op Art energy, screen-printed hand-cut collage quality, visible ink misregistration, raw imperfect edges, tactile paper grain, no modern digital gloss.
