Mail, Extra Impression of Vignette (M4 var). Complete sheet of 25,
extra impression of vignette at bottom affects four positions, without gum
as issued, rich color, trivial toning is barely noticeableVERY FINE. THE UNIQUE EXTRA VIGNETTE IMPRESSION IN A COMPLETE SHEET OF 25 OF THE 2-CENT BLACK & RED GUARD MAIL ISSUE. ONE OF THE MOST OUTSTANDING ITEMS OF GUAM PHILATELY.
The vignette was printed one stamp at a time, which made it possible for an extra single impression to appear on a sheet. This is a new discovery and becomes the unique basis of a future Scott listing. (Image)
