People who visit the museum between 6pm and 8pm on Saturdays will receive an Octopus cardholder with the image of a masterpiece by an impressionist. The picture shows the four different Octopus cardholders to be given away. They all have the images of impressionists' masterpieces from the collection of the Musee d'Orsay, Paris.
