Childhood of Famous Americans, aka COFA, - is a biographical, vintage book series (published in the 40's through the 60's I believe) about the lives of famous Americans like Louisa Alcott, George Washington, Clara Barton, Paul Revere, Abe Lincoln etc.
These are easy-to-read chapter books with black "shadow" illustrations. The stories focus on the lives of the individuals when they were children. In a short time we read through a quarter of the book. Here is a "problem" we have - mom reads a portion of a book aloud one day - with the intention of reading a bit each day. Being that my children are a lot like me - they cannot wait to find out what happens and one or the other will pick up the book later and read a chapter (or two or three) or they might finish the book altogether!
The stories are written in a way that is interesting to both girls and boys regardless of whether the biography is about a girl or boy.
We have read about 1/2 dozen of these books aloud - and I recently bought a set of 10 for only $20 (that included shipping!) A great price being that a lot of these books sell for at least $5 (plus shipping).
The 10 I received today were all about famous females (all the other ones we own are about males) - so I'm sure the girl is happy about that.
Amazon has republished a bunch of these books and I believe a number of famous folk have been added to the series. I prefer the hardcover vintage books.
