Thanks for reading, I hope to improve the analysis over time. I spent the last three years building a unique database that contains the complete paintings of ~40 of the best known artists of the twentieth century. I was motivated by reading about the large percentage of works that are forged or misattributed. I had always just assumed there was a single database listing how many works artists created, average size of the works, changes in materials over time etc. (similar to sports stats). After asking around and learning no such database exists I decided to build one. Getting my blog out there has allowed me to meet with a lot of really sharp folks like yourself who are helping me refine the analysis.
