You might want to read King Leopold's Ghost by Adam Hochschild. It pretty much covers the whole sordid situation and impact of Belgian colonial efforts.
It's taken a couple of years but I am now one Colonial Note away from having a note from each of the original thirteen colonies. This my latest acquisition.
Very nice note to add to your collection. I have A 15 shilling note from Pennsylvania and what I really like about the note is it printed on the reverse side to counterfeit is death. Does your note have that?
