I love these personalized vintage style posters from Alexander & Co, such a great idea! I've seen people use posters as their guest book by having a slightly larger mat & having their guests sign it & this would be a perfect choice if you wanted to do that.
Names, locations, dates, type colour & hair colour are all customised.
I also think the location options would be a lovely gift in memory of where you met, your first date, where the proposal was or perhaps even of a holiday you took together?
There are also save the date postcards & thank you cards available which would be a great option for those looking for something a little more unusual, & magnets which would make fantastic save the dates or favours.
There are a lot more designs available, I had a tough time picking which ones to post!
