The postcard was divulged from the 80s of the 19th century. The turn of the century was already a popular fever. In a natural and spontaneous way, there was a desire to use this medium to congratulate Christmas and the New Year. We present here a sample of copies, from the Carreras-Candi donation, from the first two decades of the 20th century in Catalonia and other countries: Germany, Denmark, France, the United States and the United Kingdom. With this exhibition the Museum of Montserrat wishes you what these postcards express plastically: happiness and prosperity for everyone.
