Gutenberg Bible "proof sheet"
These two conjugate leaves, one of which is blank, contain the text, from the Gutenberg Bible, of Exodus, chapter xxxii, verse 25 to chapter xxxiv, verse 20. This sheet contains textual errors not found in other copies of the Gutenberg Bible, as well as other typographical variations. There has been some scholarly speculation as to the role of this sheet in the production of the Bible, but no conclusive judgement has been rendered. (From: Joel Silver, The Bible in the Lilly Library, 1991.)
