This poster is currently unbacked. At check out, you will be given the opportunity to add backing which would cost $145 and take approximately 6-8 weeks.
Linen backing is the industry standard of conservation. Canvas is stretchered and a sheet of acid free barrier paper is laid down. The poster is then pasted to the acid free paper using an acid free paste. This process is fully reversible and gives support to the poster. A border of linen is left around the poster and can be used by a framer to mount the poster so that nothing touches the poster itself. Backing is what we recommend for framing, and for any poster needing restoration.
English and French language poster Meet 70 Nations at EXPO67 Montreal, Canada, April 28-October 27 - 1967
Well, you could meet 70 nations at the Expo, but only 38 of their flags made it on the promotional poster. Just saying, Nice graphics for your favorite vexillologist. (thank you Sheldon for Fun With Flags)
