In the November issue we cast our minds back 125 years to the first commemorative issue of the United States, the 1893 Columbian Exposition set, and examine how it transformed relations between collectors and the postal authorities. We also investigate the birth of Czechoslovakia, 100 years ago, following its development from hasty provisional issues to classy engravings, and take a closer look at the clever British stamps designed by Tony Meeuwissen in modern times, with their subtle nuances and visual humour. Our regular Commonwealth Classics feature admires the first issue of the Gilbert & Ellice Islands, our Great Engravers slot tells the up-and-down story of the great French artist Pierre Gandon, and our GB Themes pages consider the ways in which modern architecture has been depicted on stamps. In our news pages, you’ll find full details of Royal Mail’s new sets celebrating the Harry Potter films and Christmas, as well as interesting new issues from around the world. And, as ever, our columnists and our readers offer plenty of insightful opinion.
