Mid-century modern room Divider/Bookcase by Evans Clark for Glenn. For some reason, I never saw it before and now I have seen three of them in different places. The colored panels slide in a track so that you can recompose the configuration or hide clutter. The juncture between the two bookcases is hinged so it can be flat or the two book cases can be at an angle or twice as thick. This is an amazing idea from the 1950's.
