Abstract: The Australian Aboriginal art market is difficult to predict but armed with a tool, such as this handbook, banks, portfolio managers, investors, collectors and art market observers can navigate their way through the art market with the confidence assured by this insightful analysis. This is the expanded second edition of the Investing in Australian Aboriginal Art Handbook. The first edition was published in 2009. The results of 420,000 Australian art auction sales were reviewed and 20,288 Aboriginal artworks selected for analysis and testing to produce the Australian Aboriginal Art Index™ - AAAI™ and the Indigenous Art Index™ - IAI™. The credibility and integrity of these results and the information found within this book rely on the objectivity of art, and the contents are in no way influenced by the imprimatur of the ArtTrust.com.au sponsoring its publication.
