This is the "Local Interest" section at the Barnes and Noble book store in the Los Angeles Grove shopping center. It's all about how to grow a plant called marijuana. Apparently this is of great interest to local people in Los Angeles. I remember going to a Barnes and Noble in Baltimore , Maryland once and the local interest section was mostly full of books about crab.
Here is a video of mine from a while back where I visit a Kentucky Fried Chicken that turned into a medical marijuana shop.
