The flag of Costa Rica has two forms.
Other than the Government, a citizen or entity can show only the striped flag and not the coat of arms. And frankly, like many other red, white and blue flags there is not much to be said - yes, the red is martyrs' blood again.
What makes the Costa Rican flag interesting is its official form, complete with the Coat of Arms. Not here the heraldic lions rampant or crowns or laurels of a European institution or family; instead a really nice picture that kind of says, "Come and visit us here!".
It has the sun, (the stars to represent 7 provinces), the lush green land between the Pacific Ocean and the Caribbean Sea, two sailing ships that do seem a little, um, outdated (but would we really want two cruise liners?). There are even some golden coffee beans down the sides.
