Campbell's Vintage Glasbake Milk Glass Coffee Mug Set Portage Manitoba

In used shape as shown, vintage set of coffee mugs when Campbells had a plant in Portage la Prairie MB. Slight wear to the logo on 1 mug but still has bright color. This mug also has a rough inner lip on one side, tough to see but you can feel it with your finger. These are from the 70s or 80s as the plant closed in 1990.
