NLM: Documentary About the Original Divine Mercy Image - Is This Really What Christ Looked Like? by David Clayton

"I did hear a story that Sr Faustina was never happy with the image either, and in the end, reluctantly agreed to its use assuming that no artist could ever reproduce satisfactorily what she had seen.
