Martin Ahrens is not a strongly listed artist, and likely his work would carry auction estimates of $300 - $500. There could be a bump in value as Hensche is highly respected and was the mentor and teacher to many realist and figurative artists (including a major artist for whom I was an assistant). Essentially, from a marketing and sales standpoint, the value is moreso in the subject of the painting than the author of the painting.
