I, too, am looking to find more information about the artist. I have had a Letterman that is titled Wild 70's Psychedelic for 30 years and still love it. It is the focal point of my living room. I have seen a number of this artist's paintings for sale on
http://cheap-r.com, but have not been able to learn anything about the artist. I saw an answer on another website that said there are three painters named Letterman; Martin Letterman, Antoinette Letterman, and G. Lettermann. Perhaps it is one of them. Usually an artist wants to be known. It is interesting that it has been so difficult to find any information on this artist. If anyone learns anything about this artist I would appreciate knowing what you find out. I just saw a post by Heathfield that said the paintings were cranked out in mass by an Indonesian company. That would make sense as to why the artist information is so elusive. If that is so, I am sad that I cannot thank the artist because I love the painting. I do recall that years ago I visited a furniture or drapery shop in Salt Lake City that had an upholstery fabric that exactly matched my painting.
