This is U-Needa-Book of Bandon, Oregon. I discovered this bookstore last summer during my vacation up the West Coast and have been meaning to post an image since then. Just came across it again on my computer. Better late than never?
The store is literally about 10×15 and occupies what looks to have formerly been a fishing shack. Sadly the shop was closed when I walked by, but is was surprisingly uncluttered when I peaked in through the window. Apparently it is a satellite location of the nearby Beach Loop Books.
