ABSTRACT:
An engraved image identification card has a translucent planar base member with a multiplicity of engraved scores extending into one of its surfaces with an opaque layer positioned adjacent either the engraved side of the translucent member or the non-engraved side of the translucent member opposite the engraved side to provide enhancement of the contrast between the engraved and non-engraved regions in the translucent member.
