Dear Beverly,

Thank you for your request and patience. This is an offset print after a painting from the collection of the M. H. de Young Memorial Museum. The print or poster has the measurements of 39 x 26 inches and seems to be in good condition.
An estimate would be between 5 to 10 USD.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With best regards, 
Georg
