trees for Salzburg exhibit

The bonsai club Salzburg, Austria will have a public exhibit this coming weekend. They asked me to provide a couple of trees which should appeal to the broad public. I chose the Rocky Mountain Juniper as it is a good example of a really old collected tree. And it is around or more than 1,000 years old. This appeals to journalists (tv expected) and the broad public although it is not so important.
And then the Japanese maple looks like folks expect a Japanese bonsai to look like.
