The best-when-purchased-by date was November 8, 1996.
The dressing was very brown. Naturally, I opened it. It smelled like... dust:
This bottle of salad dressing is significantly older than a previous find, my pre-9/11 Raisin Bran, which only went back to August of 2000.
Okay, I admit: I'm actually lying about all this.
There were two bottles. (The other had a sell by date of December 1996.)
