Artist Alexander Ryazanov
 

Please, if someone knows, tell me about the author.

And about the picture itself.

The letter "b" in my opinion here for ponta, since this thing is obviously a deep post-revolutionary.

Angel with a cross like an angel with the Alexander Column on Palace Square in St. Petersburg, and painting, it seems, more or less modern (it seems to me, not before 60-70) - here I agree with Kirill

Post-Perestroika.

100%- no!

I do not know what's, but in any event, no later than 1980.

Well, I do not know, I do not know ... You know better picture of something you have before your eyes. And yet it emanates from some depression, which is characteristic for the beginning of 1990. And the plot is typical for that time. Just in 1991, was renamed Leningrad back to St. Petersburg, and many of the former contrasted with the present. Actually, I showed some affinity with works by Yuri Kozlov A. (born 1938).
