AP ceramic trinket tray with lace-like embroidery effect

A very pretty ceramic trinket dish with a beautiful, shimmering glaze in various shades of blue, gray, and light brown. The decoration is also very interesting: a delicate raised design that I believe was created by applying lace or embroidery to the clay before firing. The shape is original: a rectangle cut at the corners, which are slightly folded inwards. It's elegant and finely crafted, with clean, crisp edges and smooth details. It's a beautiful piece of handcrafted work by a ceramicist who signed it AP on the base, but I haven't been able to identify them yet. My investigation is ongoing, so if you have any information, I'd be very grateful. It's in perfect condition, with no cracks, chips, or even a single nick. It measures approximately 20 cm by 18 cm, with a maximum height of about 7 cm at the rim.
