Kostecki began her career in professional wrestling as a way to learn how to defend herself outside of the ring. She held many
titles in her career, including the
NWA Women's World Tag Team Championship three times between 1956 and 1960 and the
AWA World Women's Championship in 1961. She was then
booked into a match with Byers in Indiana for the newly formed
American Wrestling Alliance (AWA) in August 1961, but Byers
no-showed. Instead of their scheduled match, the AWA booked a
battle royal, which Banner won to become the first
AWA World Women's Champion. She
vacated the title when she moved to North Carolina with her husband and child. During her career, Banner had her nosed ripped up and her elbow dislocated. Banner claimed that she retired in 1977 after June Byers, who owned the NWA World Women's Championship, retired because of a car accident, and that
The Fabulous Moolah had cornered much of the national women's professional wrestling scene with her trainees and herself, which left Banner with nobody to wrestle in the Carolinas. In her last twenty years of wrestling, Banner was only defeated twice: once by Moolah and once by
Belle Starr, both of whom used the ropes for leverage while
pinning Banner. == After retirement ==
