Hello - Thank you for your question. This sounds just like Paul Detlefsen (note spelling) subject matter however without a painting on site it is hard to access the authenticity. There are a number of books now that record his work as it gets more known. Here is a list of reference books from Ask Art. http://www.askart.com/
It seems (as you see above) that there are outlets of his work that would be better at accessing this works value and are in the business of selling his work.
Askart does not offer their names readily on their website. I would follow up by contacting Askart, as there are over 250 questions on their site regarding the artist and his work. I am sure they could connect you to an expert or gallery who can tell you more about the value of your painting.
I hope that helps, Dori

Thank you for taking the time to help me, but I still did not get the answer I was looking for. I know you gave me some websites that may answer my question so can we compromise and cut the $15 fee in half?
Hello - This is a reference service. We can not appraise works of art or antiques by email. I am sorry that this was not what you were expecting.
You would have to contact JA to discuss the matter. So sorry. Dori
