I, too, have a large self portrait drawn with colored, bold charcoals that he drew and signed at a club where he appeared in Florida. My Mother was in attendance in the 60's and had the portrait framed and kept the newspaper article of him clipped out and posted on the back of the picture frame. It also says Howdy and is signed Kelly. It would be interesting to take to a gallery to identify it's worth. She hung it on her living room wall for over 40 years.
