On the egg at the bottom is the name of the original work and its author, as well as the author of the egg painting and signature. The egg created and signed by talented artist Elena Petrova-Motovilova from Belarus. Meticulously detailed, painted with single hair special brush under the loupe. Few layers of lacquer were applied to the surface to enhance its beauty. Also usually she uses 24k gold leaf paint to beautify detailing. There is a high probability that there is gold on this piece too. An egg is pretty big - there are some photos, depicting the dimensions of the item with a ruler.
