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.
With festive aplomb, Borough announces San Francisco’s reentry into the world after recovering from the devastating 1906 earthquake. The Portola Festival was named after Gaspar de Portola, the Spanish explorer who discovered the San Francisco Bay 140 years earlier. The U.S. Pacific Fleet participated in the five-day event, as did the British, German, and Dutch, who sent warships.
VERY rare early California poster.
