Let me put it this way: Ð¯ÐŸ is not recognized by anybody else than Ivanov who states the working period to be 1872-1898. OK fine, but let's take a look at the hallmark. Ahaa a kokoshnik looking right. That means 1908-1927. Summa summarum: Prokhorov works to 1898 and then not a sign of him whatsoever. He has disappeared completely for about 15 years and suddenly he pops up from nowhere and makes a purse ???? Mind my saying but isn't it a bit far fetched or what do you think? Prokhorov? No way I would say.
