Unpromoted naive artist

[ПростоФея]

Help resolve my doubts. Most recently began collecting collection Naiva exclusively for home use (Well prolong me), and in this way met with such proposals:

1. Petersburg naive artist Julia Andreyevna Vasilyeva, now deceased. She worked as a cleaner, paint, and much copied by introducing a copy of the original naive coloring. From the press release for her exhibition "She likes to make copies of pictures, and copies only those pictures that she most liked, most people, and landscapes. In this case it of little interest to the original author's name. Anyway, she does everything in its own way."
After the death of several dozen of her works were in one of the famous Saint-Petersburg galleries. Prices - from $ 1000 to 2500. If not mistaken, exhibited almost the only time in the same gallery in runet information is extremely small.

2. Buryat artist primitive Polycarp Ermolaevich Sudomoykin. Open the head of the Fund's ethnogeographical research, he also helped in 2007 to organize an exhibition in Central House of Artists. http://mk.burnet.ru/index.php?option...iew&id=503
Asked about the price the answer was "1000 euros"

Help understanding adequate to tell me whether the price of talented, charming (to my taste) the work of unknown artists?
