The sight of a long-lost favorite candy bar from childhood can bring back a flood of memories. While many nostalgia-focused websites and YouTube channels can give you a visual glimpse of the wrapper, nothing beats actually getting your hands on that candy and being able to take another bite. Some candy companies have obliged and brought back classics over time like Astro Pops and the Reggie! bar, but others remain lost to history.

That doesn't mean that, if you haven't seen your favorite in a while, you should assume the candy is no longer available. Some candy makers have reduced the market they sell in to certain regions, and you can check online to see if any candy stores will ship your favorite products to you. However, many candies really faded away, either due to changing tastes and poor sales, or in some cases, legal issues. Candies come and go each decade, but there are some that were popular back in the 1970s that stand out among the crowd. Here's a look at 12 classic candies from the '70s we wish we could have back.

The Marathon bar, introduced in 1973, was one of the more unique candy bars because of its shape: an 8-inch braid of chocolate-covered caramel. The wrapper even had ruler markings drawn on one edge (Did anyone actually try to use that wrapper-ruler after finishing the candy?), and the name was meant to describe how long it would take to finish the bar. It did take a while because that caramel was thick and chewy, and people joked about having to be careful of dental work when eating the candy. However, the bar didn't sell that well, and by 1981, Mars pulled the candy from stores.
