coverLife Through the Ages, 1946.
By Charles R. Knight.

I remember borrowing this book from the library during my elementary school days.  As noted in Czerkas and Glut,
"For this book [Knight] incorporated a set of charcoal drawings made in 1940 which were widely circulated among
other artists for reference purposes."  The book also contains several black and white copies of Knight's paintings of
prehistoric animals.  Also included are a number of charcoal drawings of living animals.  Note that only four of the
illustrations in the book are of dinosaurs (well, five if you include the illustration with the Archaeopteryx, below). 
Maybe for this reason I am always disappointed when I look at this book.

A commemorative issue of this book was published in 2001 and can be bought for less than $10 at used book websites. 
Original copies of this book are often listed for sale at prices ranging from $75 to $200 or more.  Do not pay this
amount!  Take your time, as nice copies occasionally show up for far less.  I purchased my copy in very nice condition,
with dust jacket, for $25.

"Parade of Life Through the Ages" article in the February, 1942 issue of National Geographic magazine.  Get a
copy of this issue, by the way.
