Vintage white bow tie mens evening dress single size 15.5 cotton repp self tie Q

If you can't quite remember how to tie a bow tie, please let me know when you pay, and I will include an instruction card with the bow tie.

Condition: Vintage bow tie, around a century old, but still in superb condition. Has been recently laundered but not starched. Previous owners' laundry marks at the back, with a small rough area where an "iron-on" laundry tag has been removed, many years ago.
