Customer Magazine
Markenzeichen

More than 100 years ago, company founder Heinrich Köhler published “Köhler’s Philatelic Magazine.” Since 2021, we have proudly continued this tradition. The German title “Markenzeichen” is a deliberate wordplay — meaning both “trademark” and, in a philatelic sense, “stamp feature.”

“MARKENZEICHEN. The Philatelic Magazine” — that is the title of our customer journal. And the name truly says it all. “MARKENZEICHEN” stands for current and exceptional articles, reports, news, and a wealth of insights from the world of philately.
