The images have been scanned by Kurt Stueber, Max-Planck-Institut fuer Zuechtungsforschung, Cologne, Germany. We thank Mr. Stueber very much for the allowance to show some of these fantastic works of art on our pages.
You will find there also a lot of other exiting books (for example Darwin's voyage on the Beagle etc.) and hundreds of plates of unbelievable beauty in medium and very high resolution.
