The full color catalog is of DIN A4 (21x29.7 cm) size with 72 pages including the covers. They received over 450 postcards and the handicapped persons under the protective care of the organizing foundation selected the most intriguing samples for a wonderful calendar.
Many thanks to the organizers: Peter Küstermann, Oliver C. Huck, and Diakonie Stiftung Salem, Minden, Germany. And my collage in the catalog is here.
