I love to travel, and would like to receive postcards that are unique to your country. I'd also like to receive cards from the well known attractions from your country and area.
If you are from the USA, I'd like a postcard from your state with a state map, state flower, state bird...
I plan to cover a large trunk with the postcards received.
I enjoy seeing the stamps on the cards, and I don't mind if your card is enclosed in an envelope.
I don't usually care for stickers so unless it's extraordinary, please save them for someone who would appreciate them.
