One of these stamps is a genuine stamp and the other(s) is a forgery. Can you tell the difference? If you are having trouble, see the "hints" and answer below.
In the genuine stamp the point of the left panel ends just past the colon in “EMP.” In the genuine stamp the right point ends just above the middle of the second “O.” The distance between points is 6 mm vs 4 mm in the forgery.
