All applicants who completed an application file receive a certificate of participation in the Luxembourg Art Prize selection round, whether they are finalists or not. This certificate can be downloaded online from your applicant space after the ceremony at which the winner is announced.
This only applies to participants in the 2020 editions and subsequent editions. It is not possible to obtain a certificate of participation for the 2019 or any previous editions. In this specific case, the receipt of payment of the registration fee is the only document that can attest to participation.
