This is part of an enormous mural showing the ecological niche for the Lake Claire area of Atlanta. You can read about the history and creation of the mural here and here – it was a largely volunteer project and is 343 feet long in total. And you can see it on Dekalb Ave near the Lake Claire neighborhood, which is a great place to do a walking tour and see some really pretty homes. No lake, though – the neighborhood name comes from the intersection of Lake Ave. and Claire Street.
