Antique Berlin Porcelain Portrait Plaque KPM - Mozart

Swap description:

Genuine antique Berlin Porcelain plaque/portrait of Mozart in brass frame with domed glass cover. Approx 5" across.
Written on back of frame = Wolfgang Amadeus Mozart in Berlin Porcelain, L.Dosche 1788

I have put the value at £30 although if it is 18th century KPM, it is probably worth several times that amount. I did have another similar plaque (different subject) which I tried to take out of the frame to discover if it was signed on the back but in doing so broke the glass. This was years ago and I can no longer find the other plaque.
