Most excellent background and the research, Deeman. We are currently flooded with commemoratives from a growing number of issuers, many hardly more than cutie-pie pictures in metal, some blatant attempts to squeeze money out of the get-rich-quickly crowd, some political statements forgotten within weeks after issue and a few commemorating something worthwhile, like a polar expedition that established a weather observation station in snow and ice. Would we have been as aware of the the danger of climate change today without the hard weather data coming from the poles? I doubt it.
It takes perseverance and determination to cut through the thicket of nonsense issues and find those few that remember the worthwhile. You did that with this issue. Thank you.
