Vintage or antique porcelain "china head" doll head, likely of German origin, dating back to the late 19th or early 20th century.
It features molded and painted black hair and facial features, including rosy cheeks and red lips.
The two holes at the base of the shoulder plate indicate it was designed to be attached to a cloth or kid leather body.
Similar items were often made by companies like Hertwig and Company or Alt, Beck, & Gottschalck (ABG).
The piece appears to be a shoulder head, a common style for these types of collectible dolls.
