Nothing like the beautifully photographed and dissected Goldfink that you have shown us, but just for general interest at the Goldfink user level/pen promo gift level:
This was probably an employee recognition from the US Sector in the 50's before the Wall went up.
The map in the background is of the Russian Zone and from about the same time. The map was sponsored by Goldring.
Peice of history, put before us. The US in 50's Germany, preferring GOLDFINK for gifting an employee is, itself a great honour for the pen manufacturer. Thanks for sharing.
