The Graham-White Type VII Popular was an early British aircraft designed by J.D. North and built by the Grahame-White Aviation company with the intention of producing a low-cost aircraft to popularize aviation. It was initially produced with a 35 hp Anzani 3-cylinder Y configuration engine and offered for sale at a price of less than 400. Despite its low price the aircraft included structural refinements such as hollow-section interplane struts. It was first flown in 1913.
