Antique Art Nouveau Pewter Wall Plate "Woman with Flower"

This is an antique European Art Nouveau pewter wall plate, likely German and dating to the Jugendstil period around 1900. The plate features a beautifully modeled woman in profile with flowing hair and stylized botanical elements, all characteristic of turn-of-the-century German metalwork.
Measuring 9¼ inches from point to point and ½ inch tall, the shallow rise and expressive relief indicate it was created as a decorative wall or cabinet plate (“Wandteller”), not for table use.
A small lowercase “a s” hallmark appears on the reverse. Based on this mark and the modeling style, the plate is attributed to the German designer Albert Schickerling (active 1895–1915), whose workshop produced similar Jugendstil pewter bas-reliefs.
Condition:
Surface scratches and small marks from more than a century of handling and display. The patina is original and untouched, including a small naturally iridescent patch on the back typical of aged pewter. There are no cracks, dents, or structural issues. I have photographed the surface closely, including the imperfections, so please enlarge all photos and review them carefully.
