I have for sale a Georg Jensen Acorn Sterling Silver Spoon-8" in length.  There are a few scattered dot stains on the mouth of the piece which I have tried to photograph.  Very faint but present in a gray color-blends in with the silver.  No monograms.  I believe this Acorn piece to  be post 1945.  It is clearly marked "STERLING" and "GEORG JENEN".  Quality piece and heavy silver.  I offer free shipping within the USA.  Johan Rodhe designed the Acorn pattern for Georg Jensen in 1915.
