Have you heard of "Flood the Streets with Art?" I just stumbled on to it several days ago. The idea is to not shop on Black Friday but give away a piece of art by leaving it at a public place. I thought it sounded fun so made the ATC below.
My daughter wanted to get in on it too and made this ATC.
So anyone finding your work understands the concept (and that it wasn't just accidentally left behind), including some sort of note is necessary.
Happy Black Friday whatever you decide to do!
