(Update) Terrell Smith sent me this note: "Those photos were taken by Lloyd Koenig, he owned a photography studio in Houston & was originally part owner of the Texas Brisket & Parts store building. Mark Schuman was the person who scanned those photos."
Terrell Smith gave me some high-resolution photos he got from Mark Schumann. Mark got them from a friend - possibly Mickey Wanjura Dylla's son. (I'm not sure.) Regardless, they are great photos. I was living in San Antonio at that time, so I don't remember the construction underway then.
Terrell walked me through some of the photos, so I could point out locations of the old 7-11, Dairy Queen & Ice House.
Many thanks to Terrell & Mark for sharing these photos. All the photos except the ones I annotated with overlays are high resolution. You can zoom in for a better view.
