This pink stripe is likely early Edwardian. The pink is characteristic of that early part of the 20th century. What I like about this ribbon is that is shows a ribbing running the length of the ribbon rather than across like most gros grains. The raised sections on this ribbon are created with a thicker warp thread. The best I can tell from the frayed edge is that there are three different thicknesses to the warp in this ribbon, the pink being the thinnest.
