Optical Illusion Circle Pattern - Vintage Halftone Design #3601129 (License: Personal Use)

This monochrome image features tightly spaced concentric circles rendered in varying line weights and halftone dot densities, creating a dynamic radial gradient effect. The pattern transitions from solid black at the bottom to near-white at the top, simulating depth or motion. Its hand-drawn texture suggests an antique engraving or early printmaking technique.

Commonly used in graphic design portfolios, psychology articles on optical illusions, vintage-themed websites, or as a background for creative projects; matches user intent for visual stimuli, artistic reference, or educational material on perception.
