An open book displaying black-and-white line art illustrations of stylized animal or creature claws and talons rests on a light brown wooden surface in Madrid, Spain. The book is open to two pages, both covered with multiple detailed drawings of varying claw structures, featuring sharp talons, segmented digits, and textured scales rendered with dense linework and cross-hatching. A human thumb and forefinger are visible on the left page, holding the book open. In the upper background, a closed, dark blue hardcover book, subtly embossed with what appears to be a creature's limb, is partially visible. A small red object is located behind the dark blue book. A portion of a black fabric object is present in the lower right foreground.
