I love this old marriage certificate. It has one of those weird eye in a pyramid symbols. Decoding symbology and conspiracy speculating is popular these days ever since the Da Vinci Code book and movie.
It also has a lovely bible book image on the bottom with a scripture phrase that is common in wedding ceremonies. The wording on this certificate is...
What God hath joined together, let not man put asunder.
