Tell about Your Postcard Collection

What kind of postcards do you collect? 

Is there a place in Italy (or somewhere else) that you like?

Are there themes in postcards that you try to find?

Is there an artist, illustrator, photographer, or publisher of postcards that you collect?

Do you have a postcard that you can't identify?

Post your interests and your questions here.  I'll try to help, and others who read this blog are welcome to help, too.
