Compared to its current logo, the old version features its red roof more prominently and the Pizza Hut font is bolder and in black.
Pizza Hut used the original logo from 1967 to 1999, when it was the by far the biggest pizza company in the world.
"Pizza Hut is an iconic brand that is engrained in the hearts and minds of so many of our customers, we felt it was our job to make our creative reflect both the rich legacy of Pizza Hut, as well as nod to where we're headed," Marianne Radley, Pizza Hut's chief brand officer, told CNN Business.
The logo is the latest change for Pizza Hut as competition tightens with its closest competitors, Domino's and Papa John's.
In May, Pizza Hut changed the recipe of its "Original Pan Pizza" with a new cheese blend, sauce and pan.
