||Linen backed antique poster for Pan American World Airways to travel by Clipper. "Portugal and Spain". Note that this is the earlier version which has the clipper aircraft in the poster. (A later edition issued by PanAm has different wording and does NOT have the clipper airplane.) The vintage lithograph features a matidor in the center with his shadow showing behind him. In small vignette windows there are images of the old cloth windmills and ancient castles and buildings. The top left portion of the image features on of the famous PanAm Clippers. A- condition.
