Similar to Little Free Libraries, a Little Free Gallery is a miniature art gallery in a small box. (See this article: https://www.smithsonianmag.com/smart-news/why-free-miniature-art-galleries-are-popping-street-corners-across-us-180977967/) DIY Lowell could supply kits for individuals and businesses to construct their own LFGs all around the city. The boxes could be locked or opened if the art is free to take.
