Illustration/commercial art is more my area, so besides the really, really well know fine artists I'm not much help.
The obvious thing to do is Google the artist's name and see if you can come up with anything. It may take a little sleuthing on your part.
To me, it has sort of a '70s or '80s era look to it - probably is "commercial" in that it was done quickly with a mass market in mind?
Just a guess on my part.
I love, love, love any original art - and if the price was right, I say absolutely go for it.
Good luck and let us know what you find out!
