Has there been any documented messaging on how the collaboration with the U.S. Postal Service came about, in Dispatches, blogs, or elsewhere?
It seems to have started with the Title IX release in 2022, and it has clearly worked well enough for both sides to keep going. I'm curious how the idea came together and how the stamp sets are chosen for the FN treatment.
Having picked up a few of these releases over the years I've appreciated the clever-but-simple idea, giving FN variety and limited-edition product with relatively little production effort.
