nothing before,or since has comapred to it...the closest was in 1999 with SW Episode I...
bat-stuff was freaking EVERYWHERE! on buses,on Taxi's (seriously!) ...toys,cereal,trading cards,sticker albums,magazines,books,candy....nowadays,this stuff is pretty much a given with any "hot" new movie coming out...but back then,we never saw anything quite like it...
i remember going into Spencer gifts that May (right after seeing Indiana Jones and the Last Crusade,where i also got to see the Batman trailer in full,glorious widescreen! ) and literally 3/4 of the store was Bat-stuff...plush dolls,shirts,,hats,sweaters (in May!),books,posters, those neon light up sign's,temporary tatoos, you name it...
of course,i bought as much of it as i could...i remember bugging my parents to buy this Batman cereal we never got because it had a Keaton plastic bank shrinkwrapped to the package,with the face and batsymbol being stickers...
a somewhat funny memory...that night when i see Indy,i went to Spencer's and got a plush 12" Batman by Applause and the batsymbol movie one-sheet poster...
...then went to TRU and they had the Toy Biz Batman figures there,so i got all 3 (Bats,joker,and Bob the Goon)
...then i came home and watched the 60's Batman film,which was on Channel 9.....so the night started off with Indiana Jones,and ended being nearly all Batman!
