This is super insightful. I had no idea about DHLs origins.
I didn't even know that DHL (a german company now) is so big.. I always thought that DHL is only a german logistic company which only serve's packages locally. And that the name implies ('Deutsche Handles Logistik')
Strange that I was completly wrong
Ironically, when using DHL to ship documents from Canada to Asia in the 80s, they would often postal mail them and pocket the difference. So we ended up using a local office service in-country to re-mail.
