Billed as the “fastest, highest, longest steel coaster in the world,” at least when the card was printed, The Loch Ness Monster would definitely qualify as one we would watch from the ground. The card has one perforated edge, indicating it had been in a set. Mailed in the late 1980s, with one 33-cent stamp and airmail sticker, but indistinct postmark.  Grade: 3
