A security document created by laminating a metalized foil between transparent layers, and modifying the outside of the foil to form a base color of the document, while leaving a window area formed by an unmodified portion of the foil. A laser is then used to ablate at least a portion of the unmodified portion of the foil in the window area to create an image. The window area includes the laser ablated image formed therein. The resulting image is transparent, with the image being visible from a front of the security document and visible from a rear of the security document.
