Here's an example of an early attempt to reach a happy medium between the candy industry and the health and fitness craze of the 70s and 80s. It's not unusual these days to see "No Fat Food" or "Lite" on candy labels now, but it was quite a paradigm shift back then.
On a side note, I have quite a few old wrappers with a similar structure to this one... Mars Bars, Snickers, etc., and as you can see, they turn into rumpled shapeless masses the second you take the candy out of them. That's why you don't see certain common old wrappers at the musuem. At some point I'll try to find a good way to straighten them out and display them.
