Unfortunately, this is one of those cases where reading the name isn't the same thing as identifying the artist. Compare this recent thread about paintings signed "S. Reed":

The signature on yours is "S. Dressen," not "S. Reed," but the situation is the same. There are a host of paintings out there with the signature, but they are bland and repetitive variations on a theme, with no evidence of creativeness or individuality:

Paintings like this are production-line work: produced by hand, by people copying from templates. The person who signs is not necessarily the person who painted it, and the name itself is usually made up.
There isn't anything wrong with buying or selling or liking "factory art." It isn't unsellable (the very fact it is produced in such numbers proves this). But the fact is you could search till doomsday without finding out where it came from - and even if you did find out, the knowledge wouldn't be of any practical use.
