Stockholm: Moderna Museet, 1968.
The front and back of the card features a silk-screen reproduction of Warhol's "Flowers" design that was also used on the cover of the catalog and the poster for this exhibition. Printed inside the card: "Andy Warhol Screens, Films, Boxes, Clouds and a Book, 1968," along with exhibition info. The catalog for this show surfaces with some regularity---this invitation never. A fine, fresh copy (infinitesimal pin hole) 5.25" x 4". Among the rarest pieces of Warhol ephemera.
