I found several paperback books on Amazon that supposedly are the Constitution, Declaration, and Bill of Rights - but now, knowing there are two versions, I have doubts the one I got is the “right” one.

I found a paperback book on Amazon that is supposed to have the Constitution, Declaration, and Bill of Rights, and I got one for all my family members for Christmas - but I haven’t actually seen it. But how do we know which version is which?
