I'm a big fan of snail mail and especially enjoy receiving postcards from friends and families whenever they travel anywhere in the world. I also think it is one of the simplest way of saying "hello".
I like any postcards as long as they're in good taste (i.e. nothing obscene or scary). Prefer to get something about:
- art and culture
- funny ones (cartoons, illustrations, etc.)
- unique or different
Handmade are okay as long as they are postmarked and comes with stamps. Yes, PLEASE USE STAMPS on your postcards and not the metered ones.
