C83a – 1973 13c Winged Letter, Imperf. Error

Add This Scarce Imperforate Error Pair to Your Airmail Collection

This pair of C83 Airmail stamps were intended to be perforated vertically.  During production, the perforations weren’t applied and these stamps slipped past the watchful eyes of postal inspectors. 

Imperforate Error Stamps: A Fascinating Philatelic Specialty

Errors are stamps not prepared according to their design specifications and mistakenly released to the public.  Errors are stamps which have mistakes in color, perforation or design.  With imperforate errors the perforation stage of production is completely omitted.  The presence of a single mark from perforating machinery would disqualify it as a true error.  This happens rarely and usually involves human error.  Many of the imperforate stamps are caught by postal inspectors before they can be sold to the public.  Occasionally, they sneak by, like this pair. 

Wouldn’t this imperforate error pair make a neat addition to your collection?  Place the pair alongside the normal C83 stamp.  Or maybe it can be the start of your new error stamp collection.  There’s always room in your album for a scarce stamp like this.  Order yours today.
