  Wm. P. Poythress & Co, 117 E Main St., Richmond VA (1892-1894)
  Wm. P. Poythress & Co, 919 E Main St., Richmond VA (1893-1917)

  Wm. P. Poythress & Co, 503 E Franklin St., Richmond VA (1919-1930)
  Wm. P. Poythress & Co, Professional Building, Richmond VA

Notes:
According to some of the artifacts below, Wm. P. Poythress & Co. were the successors to the Meade & Baker drug store, which was at 919 E. Main Street.
One of the artifacts is a receipt from 1895 that lists the name of the drugstore as:
    "Meade & Baker Pharmacy (W.P. POYTHRESS & CO., Proprietors)".
My guess is that Poythress was slow to migrate the name of the pharmacy from "Meade & Baker" to "W.P. Poythress & Co" for some reason.

A bottle I saw on eBay had a label for "Van Pelt & Brown, Inc." with the address as "the Professional Building", and it said they were the "successors to Wm. P. Poythress & Co.", The label had a date of 7-22-1932, so apparently the Poythress drugstore had ended by that date.

(more information will be added when I get around to researching this druggist)
