Continuity mistake: At the beginning "Pete" asks Violet for her autograph on a time card. She signs it and the "T" is not crossed, and when Pete puts it on the board it is crossed. Then at the end when Violet's dad buys it from Pete it is again not crossed. Also if you look at the "V" when she signs it and after Pete puts it up they are different. And lastly, when Violet signs her last name it is spaced but when Pete puts it up it is jumbled together. Her signature is different all around.
