D-cards represent cards from various types of bread/baking companies. These were usually packed in loaves of bread or other baking-related items.
Most issues were relatively standard, but some unique D-cards do exist. The D146 Donut Corporation of America Thrilling Moments set featured cut out cards from boxes of donuts.
Most bread issues are relatively scarce by comparison to other more common candy and tobacco cards. These were almost certainly printed in much smaller quantities and practically every bread issue is a somewhat difficult one to find.
Note that some bread cards listed below are considered as parts of other issues. For example, the Barker Bread baseball cards were W514 strip cards with the Barker Bread name stamped/printed onto the backs.
