This is a piece made by Sweedish artist Gwabryel of Burt meeting He Who Walks Behind the Rows. Below is an interview with the artist. This makes the second official art for the short story. This illustration was published in the book "Knowing Darkness: Artists Inspired by Stephen King"
"Children of the Corn is the second illustration; it represents the corn god (He Who Walks Behind the Rows) adored by the religious sect of children. There is no detailed description of the corn god in the text. King writes that it is just a kind of giant. So, I imagined a huge and terrifying deity with a crown of thorns because references to Christian religion (the crosses in the fields, churches) were numerous."-Gwabryel
