The things you get up to in lockdown!
The Royal Philatelic Society has put back copies of its London Philatelist publication online.
You have to be a paid up member to see some of these but those out of copyright (pre-1930) are publicly available
For my own interest I've gone through the publication from 1892 to 1930 noting all items that mentioned Liberia - a surprisingly high number. Some simply note new issues, some comment, some report prizes awarded etc, some make derogatory comments!.
In case it's of interest to anyone else I've attached the pdf file here.
