Famicom “pulse line” cartridge design (1983-1984).
"In the early days of the Family Computer, Nintendo Co., Ltd. released games with the same label design. Up to that point, Nintendo seemed to think that the best marketing strategy for their games was to keep the labels consistent in design; later on they began producing more creative label designs that varied for each game and often featured characters or scenes from the game."
