When Deportivo first used the Estrella Galicia logo it was the normal alcoholic beer. So not sure if maybe regulations etc have changed things or it's just the sponsor trying to advertise their non-alcoholic beer.
Anyways, Deportivo likes to use local companies as sponsor which is cool. Only time I can recall not using a Galician company for sponsor was the time they had Dreamcast logo ..which is still cool lol but the logo was as bland as you could get
btw there is some meaning the jersey designs, the away is basically the Galician flag, and the 3rd has a silhouette of the ancient Roman lighthouse in A Coruña where Deportivo are from.
All in all I'm happy the the design of the jerseys.
