I also agree with all 3, although my first impression of #1 was Whiteface (mostly because of the farm below) until I realized that the mountains in the distance didn't make sense for that view.
I have a number of pictures of Hillman's Highway that look pretty much exactly like #2 except for flagpole.
Thanks for posting those pics, especially #3 - it brought back memories. My Dad used to ski jump off the ramp in Berlin many years ago, and my Mom would drive us thru Pinkham Notch from time-to-time to show us the jump. Went away to college/USAF in the late 60's/early 70's, and when I came back - the road had changed a great deal.
