There've been a number of utility belts put out over the years...
This Remco-manufactured one is probably the one most familiar to Batman fans around my age... pretty lame, but it was the best we had available in the late 1970s!
This is an earlier version of the Remco set... not sure why there were changes made!
This one was much cooler, I believe this is a custom-made item!
This is a loose (and probably incomplete) version of the utility belt Ideal produced in the 1960s!
