I recently purchased this oil painting at a thrift store. The canvas is on a frame made by a NY company (Ancobilt). It is 20" x 30", with a signature. If anyone has info, I would appreciate it. Thank you.

That particular company appeared to frame a lot of works of art by lesser-known artists whose works don't appear to have much monetary value. They may have been just starting and needed to just get their works "out there" and viewable by the public in order to make a little money. Although, it's possible that some might have some good monetary value.

Is the signature legible? If so, what is the signature on it, please?

It appears to be of Middle East nature. I tried to search for anything looking/sounding similar, but could not find on the internet. It looks like Z Sunred, not sure.
