We purchase all artworks directly from the Artists (who painted them), or from Community Art Centres.

The information about artists vary greatly, and mostly, this information is provided by the artists themselves directly.  Artists also vary greatly in the way they talk about themselves and their artworks.  There are often limits they have from their families and community, about how much, and what they can say about the iconic images, and symbols in their artworks.  The works and biographies of well known artists are more widely available, whilst new and emerging artists don't have a large work biography.  As individuals, artists can be reserved, shy, or, outgoing and prolific in their stories "yarns" and life histories. There are various levels and / or interest (or confidence) in English language usage and skills.  In the majority of Indigenous Central Australian communities, English is usually not the first spoken language.

All of the paintings in this collection of artworks, come with a "Certificate of Authenticity" issued by IDAH (us), or by the Art Centres from which we have acquired artworks.
The Certificates of Authenticity, or Certificate of Provenance provides information about the Artist and the Artwork.
Although the Certificates vary, they usually have an image of the artwork;  title of artwork; and name of the artist;  and some information about the artist and the artwork.  
Our Certificates have an image of the artist with the completed artwork, and some basic, or more detailed information about the artist and the painting, (with a couple of exceptions).  
Artists sign their paintings, usually on the back of the canvas, whilst some others sign on the front.  Usually they print their name, and community, and date.  They will often write some of the story, and/or explain the icons and their meanings.  This depends on how much detail of their Dreamtime stories and images they can talk about.
