hey there
I found an old stamp book that my dad used to collect. It contains Algerian stamps along with some from Tunisia, Libya, Morocco, and Egypt so North African stamps in general. They are quite old, with some dating back to 1918, 1929, and even earlier, around the era of the French invasion.
Since I don't know much about stamps, I'd like to educate myself about them to see if they are rare and whether they hold any value.
