     THIS SERIES of twenty-five posters will be exhibited during September and October 2019 in the Interpretive Center at the Hartman Reserve Nature Center in Cedar Falls IA. 

They promote a series of public  presentations, one per month, always on the second Sunday. This third set of posters announces presentations by collector and dinosaur expert Sherman Lundy (September 8) and photographer and writer Bill Witt (October 13). 

Other presentations this year will take place in November-December. Each time, a new series of posters will be installed in connection with each pair of talks.

These posters were created on a computer, using Adobe Photoshop and related software. All source photographs in this series are derived from black-and-white photographs of plants by German photographer Karl Blossfeldt (now in public domain).

All posters on this page are copyright © Roy R. Behrens (2019).
