Vintage picture from Normandy

As you may know, I am from Normandy. The region of apples, cider, Calvados, butter, milk and cream… and cows! Once I went to a thrift store and was looking for a vintage frame. When home I took the picture out and discovered this card board picture which had been used  to be the back of it. It was a surprise for me to find such a big vintage picture.  This was on an agricultural competition the ox ( or beef???) had won a price.
