John Byrne Comic Bag Incredible Hulk Sketch 241

Well lightning struck a couple more times and I picked up these sketches also from 1979-80 timeframe from the same source.
The story on the Hulk sketch:
"John did a drawing on a white comic bag at the comic store I would visit called Grandpa Takes a Trip. It was when the incredible hulk issue 241 came out (1979) that showed a half Bruce Banner / half Hulk on the cover. John wasn't too impressed and did a great sketch of his interpretation."
