Over the years, I've run across smallish, say 8x10 posters, with the Universalist "Five Principles" (click the link to download a copy) on them, clearly intended for domestic use and personal inspiration. And I know the Universalists were not opposed to the use of religious art in the home, and particularly with children, and particularly if the art was was sufficient quality. But more that this, apart from t-shirts, we lack the elements of material culture -- the stuff -- that develop a sense of belonging.
But this was an expensive endeavor, and I can imagine a publications manager, some decades ago, having masses of unsold, faded and dog-eared prints hauled to the landfill. Inspirational poster art has withered away among the Unitarian Universalists, probably everywhere else, too. But there's no excuse for it.
Anyone on Facebook knows there's a market for it, it's never been cheaper or easier to create the images, and print it. Or, for the first time, practically ask people to have it printed locally.
NASA just released a set of imaginative retro-futurist travel posters which could act as a model for a revived poster project. Or at least as an inspiration…
