Sauba Frictographic Hidden-Picture Slips · Carlson Fable Collection

Title: Sauba Frictographic Hidden-Picture Slips
Description: 1935? Two frictographic “Image Magique” hidden page slips advertising Sauba syrups to counteract worms and warts. A child should rub a crayon on the “blank” verso and an image will appear – an image with a hidden item to find. 4⅞” x 3⅞”. $20 for the pair from Bertrand Cocq, Calonne-Ricouart, France, Sept., ’20.

These two slips combine elements this collection has encountered before: hidden images and frictography. Surprises keep coming! I am so tempted to “violate” these ephemeral treasures by trying to bring out their pictures!
