One abstract hand-painted brush swash only. Wide horizontal organic paint stroke, slightly rising from left to right, irregular uneven top and bottom edges, frayed bristle texture at both ends, varying thickness, asymmetrical and visibly handmade. A single solid filled vector shape, centered and isolated. No pen, no marker, no highlighter, no brush tool, no writing instrument, no text, no letters, no outline, no frame, no icon, no additional objects.

The image shows a black ink brush stroke on a white background, creating a stark contrast between the two colors. The brush stroke is clearly visible, with the black color standing out against the white background.
