Authenticating and registering works

The archives register all paintings and drawings realised by the Italian painter Walter Baldessarini.
An archive number is attributed to each single work, adding it to the index of the painter’s complete oeuvre and publishing it digitally in the “Catalogue Raisonné”. Walter Baldessarini personally authenticates every single drawing and painting with a certificate. For registration and authentication, every painting or drawing must be brought to the archives.
The “Catalogue Raisonné” of his complete oeuvre will be published in 2023/2024.
