I've painted this wagon several times before, but always with something inside. It is a small toy that Peggy's Mom received as a promotional item decades ago. Peggy has had it since she was in middle school. It looks great by itself, and brings back lots of memories of pulling kids in a much larger wagon, which now serves as a planter in our garden.
Again, I tried to use my airbrush to create shadows, but it didn't work. More practice is needed!
