In case you need a reminder.
When did souvenirs start?
As far as recorded cases of travel souvenirs go, these date back as far as Ancient Egypt, and include those - for one - of Prince Harkhuf, who travelled to Sudan around 2,200 BC, and brought back with him leopard skins, ivory and incense to present to the pharaoh.
Where did the word souvenir originate from?
First recorded in 1775 as meaning “a remembrance or memory,” the noun souvenir stems from the French souvenir “to remember, come to mind.” A few years later, it took on the sense of “a token” of an event or experience.
