Art prints are usually signed and numbered white frame, just under where the artwork ends, in pencil, I don't know if this one is, but it worth to have a closer look. Other then that, it's very hard to tell, it's obviously a modern piece, probably from the past 40-60 years, but that doesn't say much...
The bast way to trace the artist - if there's no name or signeture (check the back as well for that) is to talk to the previous owner of the print and see if you can trace it back to the artist.
