19th century Californian Art - Plein air Painting of Mount Shasta

This is one of our most precious finds from a local OP SHOP. This is an early American Californian Plein Air painting of Mount Shasta, and from our research it is viewed from the Sacramento River. We purchased this for $10 AUD with a current valuation of between $15 to 30000 AUD. The brush work and early Gesso frame which surround this beauty all point to a piece that is of some note.
