Worthington Library Book Panels are decorative wood book spines in a wood book case. There are 3 models. The website says the 'shelves' can be used to disguise a door or secret passageway! Sounds fun.
Another decorative or "faux" book shelf company is The Dummy Book Company. According to their website, "Our faux book products have graced everything from television and movie studios to the finest homes, hotels, yachts and restaurants. We have been featured in numerous magazine and print media publications." This might be a good way to upgrade an eggshell painted wall or walls of a meeting room.
