Abstract
A method of manufacturing a cell tag incorporating a call sign visible under low light and dark conditions, includes steps of providing a first sheet having peripheral edge portions defining at least one aperture comprising all or part of one or more symbols or characters of the call sign, providing a second sheet having a photoluminescence material or a thermal reflective material, and fixedly attaching the first sheet to the second sheet using a non-heat activated adhesive closely about the peripheral edge portions. The second sheet can have peripheral edge portions defining the at least one aperture therethrough marginally smaller than the aperture or apertures through the first sheet, to be visible through the aperture or apertures of the first sheet, and a third sheet can be attached to be visible through the aperture or apertures of the second sheet, and can include a photoluminescence or thermal reflective material.
