Vintage silk striped scarf cobalt blue

This striking scarf has had the tag removed so there’s no way to know the brand. I have been collecting scarves for 60 years and believe this is silk or a silk blend. There’s a pinhole, please see photos as they are part of the description. Colors are cobalt blue striped with turquoise and red accents. There’s a subtle polka dot effect that photos didn’t capture very well. Measures 52” long and 11” wide.
