Lot of three sheets featuring mixed media concept designs for boxes that would contain Collegeville "Pajama Costume" sets. c. 1960. Each measures about 7x10" and two have been mounted to black board and are sealed in plastic for presentation purposes but are easily removed if so desired. One design features die-cut window surrounded by jack-o-lantern pumpkins, Halloween cats, ghost and witch images. Another features jack-o-lantern pumpkins, Halloween cats, bat and ears of corn. Last has witches flying on broomsticks and shows trick-or-treaters. Sheets are lightly aged, but all art remains Exc. A unique lot for the costume collector from the Collegeville Archives.
