Company Names, addresses, dates:
  John L. Hagan's Pharmacy, Danville VA
  Central Pharmacy, 260 Jefferson Street, Danville VA ¹

Notes:
John L. Hagan's "Central Pharmacy" was listed at 260 Jefferson Street in a 1902 directory¹.
The bottle below does not say "Danville" on it , but I beleive it to be a Danville bottle based on that directory listing.
