Also, within the the same envelope, was this expertly made "Quindi Islands" stamp booklet
Quindi Islands might be difficult to locate on your World Atlas, since it is the creation of Patrizia's. The booklet includes three plate block sets of faux postage - the block on one side with the adjacent page showing the "First Day of Issue" cancellation.
The special "First Day of Issue" stamping - all three sets had this, as well as the plate block of the same stamp.
The back side of the little booklet's cover. I have a growing collection of Patrizia's perfectly constructed stamp booklets and these are a "Special Edition" that are quite welcome to accompany that handsome group.
