These are my two favourite ways to mount my work. Both manage to avoid using glass, which can cause far too many reflections in front of a very dark print (even museum glass).
1) Can be done once you’ve received your print by almost any high end framing shop. It’s slightly unusual so a little instruction helps.
2) Can be done at many shops but for signature on back it has to be done at this end before shipping (at Toronto Image Works). Mounting and shipping quotes can be provided in advance.
