Charming artist-signed tall tale, or exaggeration, postcard showing Boy Scouts at camp baking a giant potato.  Published in 1912 by Alfred Stanley Johnson, Jr., the Wisconsin photographer who invented the tall-tale genre.  To create these images, Johnson would stage family and friends in poses to create the story line.  He then added enlarged images of animals, fruits or - in this case - a vegetable, and cropped those images to fit into the posed background.  Finally, the composite photo was retouched to blend the exaggerated subject into the scene.  In this era of early 20th century optimism, tall-tale postcards most often praised the superiority of local soils capable of producing giant crops and livestock, so the Boy Scout image is somewhat unusual subject matter.  A desirable scouting collectible in very good condition.
