Superman (merchandising)
Sunnyland Refining Co., in 1981, marketed jars of creamy and crunchy peanut butter using the familiar image of Superman. In the 50th anniversary publication Fifty Who Made DC Great, it was noted that this was DC's first licensing deal for a brand of food.[11]
A Superman pinball machine was produced by Atari in 1979.[12]
Superman is part of the DC Deckbuilding Game by Cryptozoic Entertainment
In fact Superman had become popular to the extent that in 1942, with sales of the character's three titles standing at a combined total of over 1.5 million, Time was reporting that "the Navy Department (had) ruled that Superman comic books should be included among essential supplies destined for the Marine garrison at Midway Islands."[170] The character was soon licensed by companies keen to cash in on this success through merchandising. The earliest paraphernalia appeared in 1939, a button proclaiming membership in the Supermen of America club. By 1940 the amount of merchandise available increased dramatically, with jigsaw puzzles, paper dolls, bubble gum and trading cards available, as well as wooden or metal figures. The popularity of such merchandise increased when Superman was licensed to appear in other media, and Les Daniels has written that this represents "the start of the process that media moguls of later decades would describe as 'synergy.'"
Can't find much for Batman on wiki in terms of his early merchandising pre-90s.
