Here is a neat bottle label for medication prescribed by Dr. John Alexander Valens who practiced in Saskatoon, Saskatchewan, Canada for 45 years right up to the post WW2 years so this prescription label would date from 1907 to about 1950.

Alas they didn't put the medication name on the label so it will have to remain a mystery what Mr. Pierce was talking.  "Take as a tonic".  Hmmm.  The label measures 2 1/2" wide and it appears as if a mouse had a dose of the top of the label.  Perhaps it cured him because he didn't persist.  

If I was keeping this I would paste it to an antique medicine bottle and display it.  Up to you.

Good luck and thanks for looking at one of The Mighty Atom's sales.
