At end of the 19th century, poet and journalist A.B. Patterson was on assignment in Southern Africa for the Boer War and had been given a commemorative tin of chocolate as a modest morale booster. That tin has been discovered with the chocolate intact.
The commemorative tins were quite the collectors item at the time, but what impresses this blog is that Patterson managed to not eat any of it.
Even if this was found at the bottom of a suitcase when Patterson returned home, it would have been tempting to just try a little.
Perhaps he had two tins.
