This historic ad is from 1954. It is for Haag Drugs, which was at 6301 Guilford Avenue [G5 on map], where Brothers Bar and Grill is today.

Haag Drugs later moved across the street where Kilroy's is today. In 1954 though, Standard Grocery was in the Kilroy's building.

The slogan for Haag's is "Self-Serv Drug Store".
