Double

The term “double” simply refers to a cover have two of something. It can be used to describe the number of signatures (a “double-signed” cover has been signed by two different people) or the number of postmarks (a “double-postmarked” cover has two different postmarks). A double-postmarked cover often commemorates two different but relevant dates. For example, our Icons of 1969 cover illustrated here is postmarked twice on the last day of Concorde and on the date of the last Blue Ribband crossing of the QE2.
