Thank you for all your comments on this article!
BPL asked me for a 3-month exclusivity on the article and I gave them 20 months.
So today, I've updated the article substantially and made it free and open to the public my website. It has many never-before-seen photos and more explanations. Best of all, you can share it with Facebook and Twitter friends who are not BPL members. Help spread the word! Here's the link:
