In 1988, just before ending his first championship reign, Hogan introduced another new design, the "Winged Eagle" championship belt, which became the primary design for the next decade with many wrestlers holding this version, and is considered the most popular design of the championship. Its nickname is derived from the eagle's wings seemingly coming off of the center plate, which included the block WWF logo and read "World Heavyweight Wrestling Champion". The championship belt also had four identical side plates. Apart from the usual black leather strap, The Ultimate Warrior wore white, light blue, yellow, and purple variations. Sgt. Slaughter continued to wear Warrior's purple strap. In 1998, after Stone Cold Steve Austin became champion, he was presented with a new design, often dubbed the "Big Eagle" or "Attitude Era" championship belt. The center plate was similar to the previous design, but became fully rounded, and the side plates were updated. When it was unveiled, it originally contained the block WWF logo and was on a blue strap, but was soon updated to the WWF scratch logo and on a black strap. In addition to the logo, it read "World Wrestling Federation Champion".
