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.
The price of this poster includes linen backing.
In 1909, Bobby Hupp co-founded Hupp Motor Car Company, with Charles Hastings, formerly of Oldsmobile. Cars were produced from 1909 through 1939.
This is the only Hupmolbile poster we have have seen.
