A CLOSER LOOK AT THIS PICTURE
Here is the full screen image of the red hat on the window sill that was posted earlier on which can be found in episode 1 of Twin Peaks. Here we can see hidden 911 symbology as well. I had remembered seeing it when I watched the series and the first image I posted was not very detailed. Seeing as David Lynch is quite the stickler for everything being in its place I wonder how much thought went into this scene.
The woman on the phone is Major Briggs wife in the series.
