Glossary: T

Thematic

A single cover or a collection of covers that relates to a particular theme. Many collectors prefer to only collect covers that fit their passion. For example, we produce a series of railway, military and motor-racing covers. All these are themed covers. Themed covers are usuallycommemorative covers.


TPO (Travelling Post Office)

Up until 2004, much of the mail was sorted overnight while on a special Royal Mail train, traveling towards their delivery destination. Post carried and sorted this way received a circular date stamp postmark applied to mail sorted overnight in special Royal Mail train carriages. TPO postmarks have always been popular with collectors and even more so, now the system is no longer used. We produced covers to mark the last day of the TPO service.


Triple

The term triple simply refers to a cover that has three of something. It can be used to describe the number of signatures (a “triple-signed” cover has been signed by three different people) or the number of postmarks (a “triple-postmarked” cover has three different postmarks). It is worth noting that Royal Mail will not postmark a cover more than 2 times, so a triple-postmarked cover will probably feature at least one non-GB postmark. If a cover has more than one postmark, it is usually to commemorate different relevant dates. For example, our triple postmarked Concorde cover (sorry, we have no illustration of BCSP07IOM) has one GB postmark and two postmarks from the Isle of Man. The dates are of the last ever Concorde flight from New York to London (Isle of Man), the last Concorde flight ever (GB) and on the Centenary of Powered Flight (Isle of Man).
