There were these postcards you could buy when you traveled to different places - states, national parks, places-of-interest, etc. The postcard came in a paper sleeve and included a water slide decal for outside (or inside a window). You could write a nice letter to your family or friends and mail the postcard - then sticker the decal on your camper, station wagon, car or suitcase ! Neato ! This is one of those decals.... Most Iowa decals I see have corn, farms, pigs, cows, barns, tractors, maybe some places of interest - or a pretty country girl.
