This saguaro poster, designed by Nancy Campana and illustrated by Paul Mirocha, was a fun and educational height chart for kids. But, it can be used and displayed in many different ways. The Western National Parks Association has sold out of these. Since I have gotten a lot of requests, I am researching costs to print my own posters digitally on demand. If you are interested, please leave your name in the comments and I'll inform you when they become available.
