Here is a vintage desk or counter top sign advertising De Laval Cream Separators.  The metal sign is in the shape of a cow and has product information on both sides.  The cow is about 4 3/4 inches long.  The cow shows some dirt, scuffing on the painted surface, and some bending at the horns.  Please see the pictures and ask any questions.   

Thank you for looking.  (Inv 26,238)
