Vintage Symphony Scarf Red and Grey

Geometric triangle pattern in vibrant steel grey and orange-toned red. 2nd and 3rd pics are entire scarf front and back. Hem is hand-rolled but may have been re-done at some point as it is a little uneven. No tags but 'Symphony' written on one corner. Silk or silk-feel synthetic. There are several small flaws around edges- a mark, some snags or pulled threads, and holes that may be from removing the tag. Approx 26" square
