Company Names, addresses, dates:
W.C. Frey, Petersburg VA, (????-1915)
The bottle below does not say "Petersburg" on it, but there was a druggist named W.H. Frey in Petersburg. The 1915 "The Journal of the National Association of Retail Druggists, Volume 19" on page 1188 says that W.H. Frey sold his Petersburg drugstore to Russell & Rowe .
(more information will be added when I get around to researching this druggist)
This is a clear 4.7" bottle embossed:
label: W. H. FREY / THE Rexall STORE
