Everybody post Christmas cards but it isn’t an old tradition at all. It started in Britain in 1840, just after the beginning of the National Post Service and the Railway System.
At the present times everybody post greeting cards to their family and friends an most of them will be hung on the walls of their homes.
Most of the pictures show religious subjets like the birth of Christ or the Virgin Mary although lately some of these cards reflect a lot of differents matters like natural ladscapes. The only thing, at least from my point of view, is to wish the best to your family and friends.
During the present Christmas days 100 million cards are spected to be sent only in Britain.
