While Prince re-contextualizes images by others to redefine them, he has also failed to acknowledge those preceding photographers whose work he appropriates. For the Untitled (Cowboy) Series, this includes Norm Clasen and a handful of others. Clasen has expressed being aggrieved over the failure to attribute his work saying: "If you see somebody's copied your work, there's something deep down in you that says "I'm the author of that."'
