This 1909 postcard, which arrived in our mailbox this month, shows the old Esoteric Society Publishing House (lower left, next to the windmill) in Applegate, California.
Here's a more recent photo of the publishing house, which was still standing in 2009: www.flickr.com/photos/richard-o/3677694260/lightbox/

The 1887 Esoteric Publishing House best seller, Solar Biology, is available for the Kindle, or available to read for free here: www.sacred-texts.com/astro/sb/index.htm
High resolution scans of the post card are also available on Flickr.
