My favourite card this year wins the day for its utter daftness. It is impossible to look at without it smiling. Perhaps it is no surprise that it was sent to us by someone who smiles a lot themselves.
When you look at this picture, and after you've smiled, this is the question for Christmas Day - why could this picture only be on a Christmas card?
The car could be on any card except a serious Thinking of you kind of card. The dogs could be on any fun card. The background scene is quite Christmassy but could be on several other types of card - Thank You, Birthday, etc.
As far as I can tell, what makes this a Christmas picture is the dog's Santa hat.
Headwear can be an accessory but as it is so close to a face and so visible it makes a big impact - in the recent cold spell I noticed that all manner of men in woolly hats look largely the same age whether they are in their 30s or 70s.
The baby born today grew up to be a man and we only have one record of his headwear. One day he was given a crown of thorns, his coronation as king. And on a cross hung the crowned king from Christmas, the Saviour of sinners. In the partying we must find room for a prayer.
