Just curious. I've been googling it and I can't find any real history on the use of them. What's the earliest you can remember seeing one?
The reason I ask is yesterday I was talking to my parents about it and they were real confused. My mom kept asking if guests were supposed to sign in and my dad didn't understand why anyone would bother writing in one when they really just wanted to go sit and eat. I had to explain that you just leave them out and people write their advice/wishes/etc. for the couple. They still didn't seem convinced. Are guest books a new thing or have my parents just never paid enough attention?
