Sometimes paybacks are great.Dr. Roger Marshall found that out last week as he received four sunflower paintings from Great Bend High School art students of Carol Selle. Three years ago at the USD 428 Education Foundation Dinner and Auction, Marshall had bargained for – and won – a single sunflower painting by another of Selle’s students.Through a series of miscommunications, the young artist was unaware that her painting was being auctioned for keeps. Marshall, whose daughter, Lauren, is an artist, said he totally understood the artist’s creative spirit and attachment to the picture and graciously returned the painting.
