Yes, it is a complete plane... not a good picture, sorry. Note the smaller version/model next to it... it has a model pilot in it which shows where the seat is. This airplane was indeed home made in the 1920s by a high school student and it barely flew... or actually I should say hardly flew... (how's that for some hints?). This is a replica constructed from descriptions from the original builder, who went on design some other airplanes that flew much better than this one.
