Mudcat is my pick and I see Muddie or Muddy playing a fiddle by the Delta. Gosh I wish I could draw what I see in my mind. He could be by a river which would unite mountains and delta. Muddie is repersenting both blues and folk music I take it. I'ld be happy just to have Muddie on the shirt, about 3 inches tall on the left side of the front of the shirt, no pocket. Maybe you would want him on the back and large. These are suggestions, I don't mean to be pushy.
