Okay, readers, need some help here. The photo below looks a lot like a Curtiss Model F, but I've not found any indication in my Curtiss references that they produced a hull with a double cockpit. Likewise, the hull and interplane struts look similar to the configuration used on the Aeromarine Model 40/50, but I can't find reference to a double cockpit variant. The Aeromarine AMC had three cockpits. Boeing built a twin-cockpit boat, the B-1, but the hull shape was quite a bit different. A check through Aerofiles.com showed no corresponding planes with the model name "Falcon", so I'm guessing that was the owner's name for their fun toy. Anyone have any idea what make/model this is?
As an extra bonus, check out the three old Mark Twain-style paddle wheel riverboats in the background! This suggests that the location of the photo is somewhere on the Mississippi (St. Louis?).
