During 1941 Government decided that every year in October will be the Red Cross week with stamps issued to benefit the Red cross. Using this stamps was obligatory through the whole Red Cross week.
One additional Charity stamp (Mi Z1) was also issued together with this set.

The quantity of printed stamps for this issue was much higher than the number of actually sold ones, so a considerable amount was destroyed.
