Blank Postcard of Lion Cubs, by Curt Teich & Co, 1959, Smithsonian Archives - History Div, Color postcard of four lion cubs at the National Zoological Park. They are all lying down in front of a blue background. The front of the postcard has a white border. The postcard is unused, but the message side has a printed note about lion cubs: "Baby Lions are spotted. There may be as many as five in a litter. They tame readily and were it not for the fact they grow big and powerful and might unwillingly do harm they would be nice pets.".
