I scanned these from the reprints in Feature Book #29, a comic published by David McKay Co. in 1941. There are 64 Sunday paqes from 1939 and 1940, which works out to 16 months of Sundays. And all for 10¢! As a housewife keeping track of a household budget even Blondie would think that was a bargain.
More Blondie Sundays here. Just click on the cover.
