mil Ranzenhofer designed the first JNF Landspende (Land Donation) Certificate. The purose of the Land Fund was to enable persons or organizations to contribute towards the purchase of one dunam (before 1928 this was 919.3 square meters) of land in Palestine. Certificates were modified to include several different languages. It is not known how long these certifcates were in use, but do not seem to be used today. The image of this certificate was also used on postcards (see image below).
