Two Carte de Visite business cards:
The first is by Edy Photo for Henry Hipkins Dentistry. The address is listed as the corner of Colborne & Market Sts, entrance Market St.
The back of the card lists the services available: Teeth inserted in Gold, Silver, Aluminum and Vulcanized Rubber. The Utmost attention given to the preservation of the natural teeth, and all operations performed with the greatest care and in a satisfactory manner.
There are also references listed on the back of the card! These are other dentists (JB Meacham) and physicians (R Henwood, JW Digby, WC Corson and WH Nichol)
This is of a building which I believe was a school.
The back of the card reads:
Portrait and Landscape Photographer
Along the bottom it reads: Negatives kept. Copie may be had at any time
