William Stout's airline started commercial flights from Detroit to Grand Rapids on 31 July 1926, operating as Detroit-Grand Rapids Airline. We are assuming that Miss Grand Rapids, wearing fleet number 1, is Maiden Dearborn I opportunistically renamed, but this requires confirmation. Grand Rapids was Furniture City and here we see the 'first shipment of furniture by air' - presumably also the last. The source dates the photo in 1928, but that is unlikely since the USA finally started registering aircraft in 1927. Photo from: Grand Rapids Public Library
