**Printed overlay demonstration – Tree Oil vs. Sunflowers (1888)**
This image shows a hands-on overlay comparison using printed samples from the Tree Oil Painting and Van Gogh’s *Sunflowers* (1888). The sample areas are taken from the lower-right section of the Tree Oil Painting and the jar in the Sunflowers. The stroke groove depth, brush weight, and overall directionality align visually in physical form — reinforcing prior digital measurements.
