Russian Wood Box (Pyrography?) Hand Carving, Painting.

The art work on this box is believed to be pyrography with hand painting and hand carving. It was purchased in the USSR in the 1980's. It looks to be signed on the bottom, and has paperwork on the inside. It is a hinged box measuring 6 1/4" wide, 7" deep, and 3 1/2" tall. Condition is very good. Please see photos for details.

Thanks for looking. Granny Nichols.
