Did you know that...
candles were once used to determine the cost of postage?
In 1693 letters were being held in front of a candle to determine the postage rate. The less the light would shine through, the more costly your postage rate would be. This was known as candling.
That wouldn't be the best idea with our mail now :-) Especially postcards :-)
