Prior to President’s Day weekend of 2016, Robert Warren, executive director of the Hoyt Sherman Place art complex in Des Moines, Iowa was searching through the gallery closet for a Civil War flag when he came upon a dingy painting showing cracks and water damage. Through extensive research, he would come to find the painting of “Apollo And Venus” to be by 16th-century Dutch master artist Otto van Veen (1556-1629). Value of this painting could be well beyond $4 million. For the full story and a video interview with Mr. Warren, go to the CNN website.
