Sauba Frictographic Hidden-Picture Slips

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!
