International Swan Lake

International Swan Lake

How can I locate info about Athena International, a poster printing film in business in London in 1981?

I am trying to find, or find information about, the artist Arthur Thompson who created a gorgeous painting, Swans on a Lake.
I recently bought the Athena poster version of this, copyright 1981, in a thrift store.
I am not able to find Athena International, or the painting, or the artist, on Google or Yahoo searches.
Is it possible that this painting was created exclusively for mass-production by Athena International, or that the artist painted exclusively for Athena?
Any leads to Arthur Thompson, or to artist databases other than those on Yahoo and Google, would be most welcome.

For information on artists living or dead, try sites like: “absolutearts.com” or “worldwidearts.com” and type in whatever you have–artist name, type of work, style of work, medium used, size, etc. Is it a print, a painting, a photograph, an original, a print? These things all effect the value, as does the condition. Also type their name in quotes on a search engine like www.dogpile.com “John Doe”, and see what comes up.

If the artist is dead, a gallery link might pop up. A gallery dealing with the works or the estate of an artist can give you a lot of useful information, might be able to tell you the value and if there is a market for the work.
