Lacquered miniature. Original or just a souvenir??

[Anna Ivanova]

Have presented here a varnished miniature (brooch), supposedly the original and rather old. The consideration and an increase in the photograph shows the structure of the surface in the form of flowers of the same (rhombs). I think that this film is patterned, varnished, those roughly speaking - a cheap souvenir. Or is this some kind of technology and I'm not right?
