Hand Showing Four Fingers Extended - Vintage Illustration #3044245 (License: Personal Use)

This black-and-white engraved illustration shows a right hand with the index, middle, ring, and pinky fingers extended upward while the thumb is folded across the palm. The fine cross-hatching and stippling techniques create depth and realism, typical of 19th-century scientific or instructional diagrams. The image conveys gesture, counting, or symbolic representation in a historically grounded visual language.

Commonly used in educational materials on numeracy, sign language basics, anatomy textbooks, or historical illustrations of communication gestures; matches user intent for visual references on hand signals, counting systems, or vintage medical/artistic imagery.
