Brass Art Nouveau Ashtray with Woman in Large Hat

This woman looks to me completely absorbed in her own sensual world. I love the way she is framed by the cascade of her long hair on one side, the brim of her huge hat on the other, and leafy branch overhead. And then this great hand at the very center, with index finger pointing straight up (and or caressing her neck!)

3 11/16” x 2 3/4” x 5/16” and in very good condition, with a great patina. I assume made to function as an ashtray, earlyish 20th century I believe. I believe this is brass but it seems not impossible that it is bronze.
