Wow, Douglass Bailey's also got an attractive-looking book I never thought existed in English called Balkan Prehistory, as well as the one about the exhibition you mention

http://www.amazon.com/Unearthed-Comparative-Study-Neolithic-Figurines/dp/0954592123/ref=sr_1_4?s=books&ie=UTF8&qid=1323632725&sr=1-4

However, browsing through the recommendations I bumped into this pricey thing:

Interpreting Ancient Figurines: Context, Comparison, and Prehistoric Art [Hardcover] - Richard G. Lesure (Author)

and also:

http://www.amazon.com/Interacting-Figurines-Seven-Dimensions-Imagery/dp/0979004632/ref=sr_1_fkmr2_3?s=books&ie=UTF8&qid=1323632099&sr=1-3-fkmr2

I'm amazed at the sheer number of new books on the subject of figurines, I must be getting old...
