This was probably issued for Robert Sivell's selection & participation in the 1939 Golden Gate Exposition, where one of his paintings was selected for display in the IBM Gallery of Science & Art. I believe that IBM purchased all or most of the paintings displayed, but long since sold or distributed their art collection. I have the painting title, and a copy of the exposition catalog: "Contemporary Art of 79 Countries" which has a b&w photo of the painting "Isobel".
