I have an old painting of van Gogh's bedroom (at Arles) that I bought many years ago for $4 at a barn sale. How can I find out more about it and its value?
Van Gogh painted two copies of his "Bedroom at Arles." One, painted in 1888, measures 29 by 36 inches and hangs in the Art Institute of Chicago. The other, painted in 1889, measures 22 by 29 inches and is in the Vincent van Gogh Museum in Amsterdam.
The painting was reproduced by art firms, some of which sell "canvas transfers," which are paper pictures of famous paintings attached to canvases.
Andrew Weissman, an art copier whose oil on canvas copies are so accurately reproduced they fool experts, offers copies of any and all museum artworks, including van Gogh paintings, in any size. He reproduces such costly paintings for art owners who want to replace the real painting with a copy for security purposes. He also produces oil on linen portraits (copied from one's own photo), which he can paint in either a realistic or a van Gogh style.
For color photos of such realistic and van Gogh-style portraits, write Mr. Weissman at 325 Alexis Court, Glenview, Ill. 60025; enclose $2 for a sample photo pack. For additional information, phone Mr. Weissman at  724-1195, or fax  724-1196.
It's a good idea to check out paintings; a few years back, a painting that hung on the wall in a Wisconsin home turned out to be an authentic van Gogh still life, and sold for a cool million.
