For note, I'm still learning sources for the all Bayern 70s through 80s period. Usually really confused me, to worked on Bayern kits within these era. If you are the Bayern fan maybe can share.
Bayern Munich from 1979 through 1981 classic Home Adidas trefoil in style, a simple wing-collar and a white three-stripe design both featured on this all-red strip. Magirus Deutz sponsor logo across the chest. The home shirt was worn with the red shorts and socks. Conclusion, I'm conform these shirts style was worn during the 1978-79 season, but with the adidas trefoil logo only.
