GB Overprints Society

Why have GB stamps and postal stationery been overprinted?

GB Overprints Society (GBOS) helps members and collectors to explore the many ways in which, and reasons why, British stamps and other postal material have been overprinted, whether it is for use outside the UK or for special functions within the UK.

This opens up a wide variety of avenues, which will interest not only GB collectors who want to find out other uses of their favourite stamps, but also collectors of particular countries or themes.

"The Aims and Objects of the Society shall be: ... the study of the stamps, postal markings, postal stationery and all philatelic material overprinted on the issues of Great Britain, of all countries that have at any time used the foregoing ..."

These pages will help you see some of these areas and, we hope, encourage you to join the Society. Please note that the Society only studies overprints on British stamps etc, not overprints on material of other countries.
