GILLETTE

A sharp looking font that represents the product its trying to sell.

The G and the I are most interesting. 

GUINNESS

A famous drink brewed on the emerald island. 

The Guinness logo has been designed so well that it represents the alcoholic beverage entirely within its font.

The white against a black background, the drink is a deep brown/black colour with a creamy white head. 

The serifs are small, pointed and rounded at the end, almost representing the head on the brink of overflowing the rim of the glass. The intersect of the stem in the letter N also represent this. 

THE LEGO MOVIE

An obvious concept behind a simple design. 

Its the lego movie title.
It is made out of Lego... simple 

CORREOS

A really simple concept, by simply extending the capital C's finial is slightly extended into the "o" to make it look as if it was to represent someone posting a letter?
