When Loretta Lynn is at the radio station asking why the disc jockey had lied to them about playing her record, you see the picture of her that they took at home. It is a completely different pose than the one that you saw them take a couple of scenes earlier. She is looking in a different direction and she is not smiling as much as she was when they took it.
There is a scene in which Loretta is on the porch playing guitar, and kicks the washing machine. In her book 'Still Women Enough', the real Loretta explains that they did not have electricity at that house, let alone a washing machine.
