Mrs.Elena can
produce "variant-copie"
of the themes by request. But the "variant-copies" – whatever different or revised -will still remain the author's ones.
There were cases of common practice, wherein versions were still either precise or precious
(e.g. authentic "variant-copie" of some Iliya Repin's paintings). The number of versions will be little for sure, because it will take about half a year to accomplish a "variant-copie" and life is short.
Still more: since Mrs.Elena had no special study in artwork, but came to carvings by herself, she possesses her own peculiar style of craft. Probably the way she holds the chisel is incorrect and far from classic one, but this is
her unique school.
