The Historical Museum in Sanok, Poland selected a matte polyester canvas with a weight of 175g to reproduce
the Master's Works.
Unstretched museum wrap canvas, shipped in a sturdy tube OR a box/tube combination.
It requires stretching an possibly framing.
See the video on youtube how it is done.
We advice to use a professional picture framing store to do that for you!
