in World Cup 2006 matches, this flag was used in yesterday Gold Cup match, this flag was used first - civil flag second - state flag why do they use different flags ?
The second one (with the crest) should be used only for official purposes (like diplomatic events and such), not for sport events. So, in short, CONCACAF f'ed up. But what else is new, really.
Seems to be an error on everyones part as that flag was also used throughout UNCAF 2009 as well as during various Costa Rica games that have run on Galavision, Telefutura and Univision over the years.
but Ecuador use their state flag (with coat of arms) in sport events.... (avoid confuse with Colombia ?)
