Abstract: An end wall display window particularly structured for use with a wraparound type carton in which a container matrix of, e.g., soft drink or beer cans, is sold. The display window structure preferably includes two wrap panels at each end of the carton, one on each wrap panel pair being connected to each of the carton's side walls. The two wrap panels of each pair are wrapped around portions of the outer surface of the end container in the matrix so that the wrap panels conform to the configuration of those container outer surface portions. The wrap panels are configured to define a window so that at least a portion of those end containers about which they are wrapped will be exposed to the sight of a casual viewer.
