Vintage hand painted porcelain plaque KPM antique style signed Patricia Kolb

A hand painting on porcelain, the fantasy image that of a young classical maiden with butterfly wings, in the style of antique painted 19th century porcelains like KPM, signed center right by artist Patricia Kolb. The piece, measuring 19" by 14 1/2" in its frame, has some age, though I am not certain as to just how much age---anywhere from 1930's to 1960's perhaps. The image could be a copy of a known painting though I have not seen a quick Google Lens match. Condition is excellent. There is a bubble in the porcelain at left, as created.
