When Kelly first arrives to town, she walks past a theatre, and Fuller takes the chance to promote his own 'Shock corridor' as if being projected there. However, the action takes place in August 12th 1963, whereas the movie wouldn't be released till September 11th.
When Kelly approaches the porch of the house with the room for rent, she picks up the newspaper and hands it to the landlady who has opened the door. The newspaper, as picked up by Kelly, is snugly rolled up and bound with a rubber band. But in the next frame, taken from inside as we see landlady and Kelly come through the door, the newspaper in the landlady's hand is not a rolled up paper, but one that is simply folded in half.
