I recall Stroh's making ice cream but not Sanders. No matter. This advert shows their "handy half gallon" which was available in Milk Chocolate Heavenly Hash, Chocolate Chip, Black Sweet Cherry and may other flavors as well as their vanilla or chocolate Jumbo Cones.
Their "Suggestion: some warm day soon, make yourself an ice cream cone, go outside and enjoy it. You'll agree Sanders Ice Cream is the best ice cream under the sun!"
