🎨 Athletic Club 2004 home kit

The Design: Known popularly as the "Ketchup Shirt" (la camiseta del ketchup), this kit featured an abstract, non-traditional design created by artist Darío Urzay specifically for the club's UEFA competition campaign.

The Reception: Its unique, abstract aesthetic sparked intense debate among supporters and the football community at the time.

Legacy: Despite the mixed reactions during its debut, the jersey has become a significant collector's item. Today, it remains a key piece of the club's history and is featured prominently when visitors tour San Mamés and the Athletic Club Museum.
