Great old post cards OldGum
I just love the history you can bring back through collections don't you.
Just to add a little to your post: When I try to help someone choose an unusual tree at the nursery I tell them a story about one particular Ginkgo tree in Hiroshima that stood in front of a temple.
Apparently after the Bombing the temple was destroyed and the tree was just a charred log. They had removed the rubble from the temple to build a new one and were about to cut down the charred tree when they noticed new growth coming from the blackened branches.
They took it as a sign and built the temple around the tree where it still stands today.
I sell a lot of Ginkgo trees by telling this story

I also have one in my yard.
