From this year's Far and Wide series, on the $ 1.05 Tombstone Territorial Park (YT) stamp, I came across a roll of 50 with a change in color of the stamp (white, light blue to dark blue) and a bluish spot in the sky. The roll of 50 stamps is affected by this sequence that comes back every five stamps.
