As part of the preparations for a major exhibition on the history of associations in Luxembourg City, which will take place in 2022, the museum had launched its public call of objects "Bréng däin Déngen". From 12 May until 18 July 2021, the "Wiel däin Déngen" platform invites museum visitors and internet users to choose from a selection of objects that they consider to be "must-haves". If their favourite object is also the favourite of others, it will be included in the exhibition.
