p2sp… was begun in 1996 by Antonio Nodar, when he started photographing artists in black & white and giving them a print onto which they rendered their response in a medium of their choosing.
The process resembles a dialogue, where the answer to the question posed by the photographic portrait is given in the treatment it receives at the hands of the artists.
…p2sp… is ongoing and has spread worldwide to include more than one thousand artists. The original artworks and photographs, of which the final collection comprises, are not for sale, but will be donated at a future point in time. However, a collection of personalised volumes is available for collector participation.
To mark the completion of the first one thousand artists involved, … from portrait to self-portrait … diptychs collection goes public under the form of a Volumes collection.
