Vtg 60's 70's Abercrombie & Fitch Virgin Wool Cable Knit Cardigan Ireland M/L

Vtg 60's 70's Abercrombie & Fitch Virgin Wool Cable Knit Cardigan Ireland M/L. **not sure if this is men's or women's. No size tag; measurements are consistent with a size M/L. There is this black stain on the front of cardigan; not sure if this can come out or not i have not tried because the item is wool and would need to be dry-cleaned. Missing very first button as shown in photos Does seem to run on the shorter side. Please refer to all photos for condition and sizing.
