I recently came across these examples of vintage halloween cards.

These halloween cards kind of remind me of the valentines we used to hand out as kids. They weren't greeting cards as much as they were trading cards.

We handed out valentines to all of our friends. Actually, we handed them out to everyone in the class.

I've never really seen halloween cards like this before. It would be a cute idea to have the kids give their friends "Happy Halloween" or "Trick or Treat" halloween cards.

Halloween cards could have the traditional characters, skeletons, ghosts, zombies, witches, etc. They could also have the more modern characters like Buzz Lightyear, Jack Skellington, etc.

Of course we wouldn't have to let the kids have all the fun. Adults could give halloween cards too.
