Minute Stories of Famous Explorers by Jerome S. Kates (1934)

I really dig library book sales.  All paperbacks are 50 cents and hardcovers are a dollar.  I found this gem this weekend.  It's a 1934 book that describes the exploits of 73 explorers, some more famous than others.  The format is right up my alley.  On the left side, you have a hand drawn map with the explorer's route(s).  Accompanying each map are three illustrations showing his hardships.  On the right side is a brief blurb about the man and his accomplishment.  Here is a sampling:

The cover.  The book is in pretty decent shape, save the missing spine.

The paper stock is thick and sturdy.  I can't tell if this is a children's book or not.

The list of explorers.

Part 2 of the list.

This page is on the left side and shows Lief Ericsson's journey and travails.

This is the right side and describes his accomplishment.

Here is a more obscure explorer.  Salmon Andree tried to fly over the North Pole with a balloon.  He was not successful.

Andree's fateful trip.
