Yes, this is a quilted car. the Lebanon, Oregon, quilting guild stitched this to help advertise their own quilt show.
The show featured an appearance by the quilters of Gees Bend, Alabama, and included a set of "challenge" quilts stitched by employees of The Stitchin' Post. They were to create their own quilt "in the manner of" the Gees Bend quilts. This one was made by Annette Caldwell, and she called it "Insignificant Stripes."
