ABSTRACT:
Apparatus for removing a marking from a stratum surface comprises a pellucid film in the form of a heat softenable polymeric material to be placed over a marking and a source of light energy for irradiating the marking and film to heat the marking and soften the polymeric material to thereby transfer the marking to the film. The apparatus in the form of a pen type implement provides means for energizing the light source and thereafter moving the pellucid film in single operation.
