At the co-op gallery there was disharmony because some of the walls were "good" - flat and white - and other walls were "bad" - rough stone. Nobody wanted to hang their work on the rough stone walls, and there were all kinds of attempted solutions, like a complicated lottery system, etc. I claimed the "worst" space and hung up this sign.
Also there was disharmony because the very low dues just paid the rent with nothing left over for fancy displays, etc. So... another inspirational sign.
