ABSTRACT:
An advertising device formed of sheet material having a first and second portion, one of which includes a predetermined visual indicia formed thereon, and the other portion having a non-visible or latent image or indicia formed thereon; whereby the latter is rendered visible by coating the latent image with a developing ink. This disclosure further contemplates a developing device for developing the latent or non-visible image or indicia, which includes a support arranged to receive the sheet of material so that the portion having non-visible or latent image is predeterminedly positioned at a developing station formed on the support adjacent to a source of a developing ink supply formed thereon. A carriage containing a roller is slidably supported on the support, whereby the reciprocation of the carriage relative to the support causes the roller to transfer the developing ink from the supply source to the sheet so as to coat the portion containing the non-visible or latent image or indicia to render the same visible.
