This must be one of the reasons there are so many bad sheep jokes about New Zealand. Three postcards, sent over a twenty year period, all featuring sheep. Close ups of cute little lambs, a view of a flock, and sheep as interest in the foreground of a shot of a distant mountain - a variety of ways to show pictures of sheep.
I've only been to New Zealand once, and it was on business, but I don't remember seeing a single sheep. What about all the gorgeous scenery, the outdoor extreme sports, the Maori culture, the geysers? Instead I was sent postcards of sheep.
