I'm finding it hard to photograph photos well, but these are really gorgeous, both formally as images and for the marvelous early flying machines they capture! With a little research I've figured out that they were taken at the 1909 Frankfurt International Airshow in Frankfurt am Main, the world's largest and most important early aviation exhibition, which included all manner of aircraft (from early flying machines to balloons to the Zeppelin, with a lecture by Count Zeppelin Jr., etc.) Here is the DeCaters #1 Voisin, with the Festhalle (exhibition hall) in the background. designed and flown by Belgian Baron de Caters, and Louis Blériot's (French) Blériot XI, the first to fly across the English Channel this same year. I'm not very knowledgable about early aviation, but find these completely beautiful, and know they are quite scarce, and don't they just capture a sense of the magic of flight in very pure and poetic sort of way?

Each 5 1/2" x 3 1/2". Sold as a pair. A bit of surface peeling along the far left edge of the Blériot image, otherwise in good condition, with unused backs.
