The Winterhilfswerk (WHW) was an annual drive by the Nationalsozialistische Volkswohlfahrt (the National Socialist People’s Welfare Organization) to help finance its charitable work. Its slogan was "None shall starve nor freeze". It ran from 1933-1945 and was designed to provide food and fuel to Germans. The Hitlerjugend and Bund Deutscher Mädel were extremely active in collecting for this charity. Donors were often given small souvenir gifts of negligible value as a sign of appreciation for their donations. A typical such gift was a very small propaganda booklet about 0.8" wide x 1.5" tall. More generous donors would receive nicer gifts, such as lapel pins on a wide variety of themes. Each individual miniature book, badge, badge set or toy set was only available for two or three days of a particular collection drive. So the populace would be encouraged to donate the following week and thereby collect the latest in the series.
In honor of the Tag der Wehrmacht, the WHW put out a series of booklets in the Winter of 1942-43 with fallen heroes of the Wehrmacht, all Knights Cross Bearers.
Each booklet is 2 3/4" x 2" and have 7 pages with pictures and descriptions.
