Harper Lee signed this First Day of Shooting Shooting Call "To Ollie, With Love, Nelle Harper Lee". Ollie is Oliver Emert who did Set Design work on the movie and won the 1963 Academy Award in that category for his work. Harper Lee signed very few items using her full name. I would guess that just a "First Day of Shooting Call" would be a very scarce item. Add Ms. Lee's rare full signature and I would guess this is an extremely scarce item.
