Mountains in an envelope swap - postcards

Postcards in an envelope, new (or in great condition), unwritten, black and white or coloured. The only catch is they must have a mountain or mountains on them, volcanos (and very large rocks if you are Australian, always had a hankering for an Ayres Rock pc) are acceptable. Snow or no snow.

Can you put 4, or more, mountainous postcards in an envelope and send it around the world to one partner? If you get me I promise to throw in a beach one as well.

Newbies welcome but try not to let me down as I cry easily.
