Small Mary Gregory emerald cup unusual figure

Here is a beaker with classical silhouette in white enamel over a dark green glass. The rest of the surface is enamelled with spirals in gold. It has about 10 cm height. I bought it to Dorita in the 2012 at a very low price. The handle has lost almost completely the gold, and the glass is panelled, see the last picture. Decorated by Moser, blank probably Harrach.
