Rose is Rose by Don Wimmer and Pat Brady for January 20, 1992

For people looking at this strip in the present -

As late as the mid-1990s, many retailers did not have their own in-store brands. Instead, they had “generic” products, with minimalistic packaging. Texas-based grocery store chain H-E-B, for example, would pack such products in white packaging with a sketch of the product.

These “generic” items were typically kept in a single aisle, regardless of what they were, meaning that you could, say, find dog food, shampoo, and cheese puffs right next to each other.

Once brand names became popular the generic goods aisles disappeared and the store-branded items were stocked in with the national brand competitors.
