<p>Set of ten strips of 10 two-digit color coded numerical indexing tabs, each strip comprising a backing of release paper and an overlying strip of transparent film having a coating of pressure-sensitive adhesive on its under surface mounted on the backing and cut transversely to devine ten individually separable tabs, the tabs of each strip being color coded by reverse printing the same first digit on each with ink of the same color and leaving a blank space on each tab directly adjacent the first digit, the overlying strip having a write-on upper surface coterminous with such blank spaces to enable selective application in each blank space of any desired digit for display with the adjacent first digit; only five different colors of ink being employed, each with one of the first five strips respectively displaying 0 through 4 as the first digit, and the second five strips respectively displaying 5 through 9 as the first digit, each with one of those five colors and with the printing being extended laterally of the tabs to outline the blank spaces; the longitudinal margins of each overlying strip comprising skirt portions on each tab applicable in use to opposed surfaces of a sheet to be indexed, means defining a fold line laterally across each tab to facilitate such mounting thereof, and the reverse printing extending on both sides of the fold line to enable three dimensional identification of the tabs as mounted in use.</p> |
