  M. Wertlieb, 300 14th Street, S.E. Washington DC
  Wertlieb's, Corner 14th & C Streets, S.E. Washington DC

Notes:
I can't find any references to "M. Wertlieb" in the city directories for bottlers, brewers, saloons, grocery stores, or wine & liquor dealers. I was also unable to find "M. Wertlieb" in the U.S. Census.
All known Wertlieb bottles seem to be machine-made (even the blob-tops)¹, so I'm guessing that his bottles are from somewhere around 1905-1920. The bottles below lists the address as "Corner of 14th & C Streets SE", and "300 14th Street SE". From looking on a modern map, it looks like these 2 addresses refer to the same building (currently home to Payne Elementary School).
