Jet Drive In, Austin TX. This appears to be a postcard promoting the items used to build drive-ins. Says the text: "Bright, natural light from mercury vapor Wide-Lites invites customers into the attractive Jet Drive-In at Austin, TX. Their color-corrected light flatters food. Flatters faces, too."

Food-flattering floods: there was no challenge to which the genius of American industry was not turned, eventually.
