Pre Columbian Art Series

Here are covers with examples from the 18v 1963-4 'Pre Columbian Art' series. A six limbed figure, dog, 2 frogs, a pair of bakers, ceramic vase, man, decorative stool and an overprint.  
Thank you Tiem! The ancestral figure from this set also adorned PSEs. Did any others? Was this envelope created in 2001 with the new denomination?
