Steve C, FTW.
It is a Pietenpol Air Camper.
Powered by a Ford Model A engine.
This was the airplane that made "homebuilding" popular - kind of the RV of its day. It could be made cheaply at home, and built as money became available (Got an extra $20? Buy the wood to make the wings).
Still popular to this day. Other powerplants have included Corvair power (in fact Bernard Pietenpol's last airplane built in the 60's had this). Also some have had Continental engines of 65hp installed. I would probably go for a Ford powered model as I love the radiator look.
