What was the Gutenberg Bible?

What was the Gutenberg Bible? by Danika Cooley and published by Christian Focus Publications.

Johann Gutenberg invented a world–changing machine that meant people could read God’s Word for themselves. The world could share ideas, discoveries and new and God’s Word could be quickly, inexpensively and accurately reproduced. Danika Cooley helps 9–11 year–olds discover how the printing press paved the way for the Reformation.
