Exceptionally rare original retail Bayern Munich home shirt from the 1989–1991 period, featuring the iconic number 5 on the back — the number worn at the time by club legend Klaus Augenthaler. Although this shirt was not player‑worn, authentic retail examples from this era are incredibly hard to find in such preserved condition. Early‑90s Bayern shirts were produced in limited quantities, and surviving originals have become true collector’s items. This classic red home shirt showcases the unmistakable late‑80s Adidas Trefoil design, combined with the early OPEL sponsorship style that defined Bayern’s look during this period. The number 5 on the reverse corresponds to Klaus Augenthaler, long‑time captain, Bundesliga champion, and one of the most respected defenders in the club’s history. Details: - Bayern Munich – Home shirt (1989–1991) - Original retail version (not player‑worn) - Classic Adidas Trefoil era - Number 5 on the back — assigned to Klaus Augenthaler - Highly collectible and increasingly rare in this condition A beautiful and historically significant piece for any Bayern Munich enthusiast or collector of vintage football shirts.
