I have narrowed the date range on this dress to 1974 - 1980 based on the ILGWU label and the fact that the WPL number is Gay Gibson (Gernes) out of Kansas City, MO. Garment manufacturing had pretty much died out in KC by 1980. I am trying to narrow further. Attempting to determine when "Fortrel" would have been dropped from the fabric label. Fortrel was the Celanese Corporations name brand for their polyester fabric. The patent was filed in the 60s which I was able to determine from Celanese but no one seems to know when the trademark ended. TESS and UPSTO databases so far no help. Anyone have any ideas?
