I think what I really like about both of them are the expressive quality of the drawings. Im a sucker for German Expressionism and Jay's HOF posters strike me as a contemporary updating of some of those old etchings and drawings. This one is so creepy yet gentle...Like a Kathe Köllitz compostion. I think its a pretty creative use of the skeleton with the exaggerated hand bones. To each his own, of course.
I dont really know what I think of this as a poster design, although if its a silkscreen Ill bet it looks nice in person. I do know that Rogers Hornsby (whom this is not a pic of ) was one of the greatest hitters in the game. Baseball.
