I can not determine the artist

[Amateur]

Your picture seems to me more like "art for tourists. In this case, very rarely "calculate" the artist. Moreover, he is obviously inexperienced: a horse's head is too small, but the legs are too long. However, the flavor is not bad, the feeling of spring transferred correctly. If it were not for this horse ...

In principle, the signature can be read as "A. Guidotti". Was such an artist Antonio Guidotti, 1881 - 1958. He is in the network. In general, wrote watercolor views of Venice, although he has a landscape remote from the sea areas of Italy, oil. In general, it is also a "tourist" artist, may be a little bigger caliber than the main mass. Signed it is very unstable: where is written out clearly, and where - as a "chicken paw. Initial "A" could be both before and after the name. I could have put samples of his signature (something like a signature is), but I myself doubt that this was it: you have a canvas almost new - no more than 10 - 20 years.

There is one not very clear fact: oil removed from the stretcher. This in itself is not evidence in favor of the value of the painting. And in general, so pictures are sold only at the flea markets in Russia in the West, even at flea markets, not to mention the auctions, I have never seen a canvas sold without a stretcher (even without the frame - and it is very rare).
