OK so this is cool. The Tally FLAG is an old post box that’s been repurposed into a Free Little Art Gallery by replacing the metal doors with plexiglass (is what I think it is). It’s got lots of space, and it’s built for outdoors with sturdy metal construction. And of course magnets will stick to it, so I sent them some — the address is in the map entry.
Welcome to the FLAG community, curator Holly Kratt!
