Postcards that were swap - in an envelope

Hello all,

Place at least 3 unused, unwritten, good condition postcards that are now out of date because of changes in the last few years, in an envelope and post to one partner.

For example:

There may be a new building replacing an older one. A dam may have been built across a valley. A new housing developement on what was previously farmland. A one lane street is now a 6 lane highway.

Here in Christchurch, New Zealand, many of the landmark buildings were knocked down by an earthquake and only exist on postcard now.

If you get me as a partner I will probably include an extra one , or three, with sheep on, not that this is outdated, New Zealand doesn't look like running out of sheep any time soon.
