Each year, ICOM creates an International Museum Day poster, as well as web banner, linked to the theme of the year, enabling participating museums to illustrate the theme and to attract visitors with an appealing design. They invite you to download and adapt this image in many ways and on any media, according to your wishes. They also have a bundle of communication tools to assist your museum in celebrating International Museums Day!
