The Cameo is one of my favorite KJV’s. It has an 8-point font that’s bold and readable and the overall size makes it great for reading and carry. LCBP also produces several versions of it including a wide margin edition. Here are some photos that show how the two editions compare.
The Cambridge is black goatskin and the LCBP is the Signature Series cow hide. Both are edge-lined and sewn around the outside edges.
The print in the Cambridge edition is darker, but the LCBP looks sharper. The Cambridge paper is made to be thin, while the LCBP is made for writing. Both have their advantages.
Both have the Epistle Dedicatory. LCBP adds the Translators to the Reader.
They have different concordances and maps.
