That's a great collection of maps. I noticed this map, dated 1926, describing the pilgrims arrival in the New World.
Some of the things they found were mysterious, remorseless savages, monstrous, sarcastic leopards, and colorful campgrounds.
OMG the toadstools, tremble in terror before your toadstool overlords...
The map was created by Frederick Coulton Waugh a British ex-pat, cartoonist/illustrator/painter, son of marine artist Frederick Judd Waugh, and grandson of the Philadelphia portrait painter Samuel Waugh.
