Rouse’s Drug Store
Rouse’s Drug store was located right next door to the building that housed H. N. Frachtmann’s Jewelry shop, which was the subject of a separate (and juicy) post that you can check out here.
The owner of this business was Samuel Rouse, who as far as I can dig, seems to have no immediate affiliation with the family who owns Rouses Markets.
Today, the Harris County Tax Office occupies this lower half of the block.
