I lived in Mehovyitsah in 2001 and watched as Leon is working (we were shooting a documentary) no son then was not there, he lived in the Savin. In 2001 I reached an agreement with Leonov, that he will stop dating their work. Work Leonova 2002-2003, not dated.
After that, there are again dated works in the style Leonov. However podvpis Leonova changed. Namely, in the original papers "l" has the upper crossbar. In the new work "A" sharp as a tick.
Thus, all of 1992-2001 years, all undated works - it works Leonova father. All datirovaney work after 2003 2005goda (the exact boundary is unclear) - this is probably the joint work. And judging by the signature, the signature is visible stargo loenova and new. There are other differences. But these differences in dating and signature are fairly simple.
In 2009 I was with Leonov and his son, and there was not at home no job, no trace of their mass proizhvodstva. (Which were in the active period of creativity Leonova) so I do not think that the number of works sregeya large.
Sraneniya for the proposed work datirovoannye 1996 and 2007 years
