Looking at the past

My dad’s schoolboy stamp album tells a lot of history.
German hyperinflation
Jugoslavia (sic) when it was a monarchy
Pre-revolutionary Russia and then soviet hyperinflation (by the looks of it)
China before it became a fully-fledged Unitary Marxist–Leninist one-party socialist republic
The Dutch Indies
French-Indo China
Iran as a kingdom
Lots of French Colonies
Different world…
