Simply unforgettable

All brand names are well known.  That is why they are brand names.  When one thinks of Louis Vuitton, Gucci, or BMW, one thinks of the merchandise in which they market.  Another person will envision the logo that represents these products.  Taking the Louis Vuitton logo, for example, it is comprised solely of the uppercase letter L juxtaposed with the upper case letter V.  As separate pieces, they would only be letters of the alphabet, but when combined in this particular manner with the V overlapping a portion of the L, it becomes an internationally recognized symbol.  But what is it that makes this logo, as well as many others, so unforgettable?

In this particular case, it is a combination of simplistic design, and its ability to convey information. 

This logo, or logotype, is comprised of two singular components;  two letters, aesthetically placed form the logo for Louis Vuitton.  The significance of the two letters, the L for Louis and V for Vuitton, are easily identifiable as the initials for this brand.  The correlation between the initials and its usage in the logo is understandable.  Were the brand to suddenly incorporate another letter, the correlation would not be as clear and the probability of the "new" logo being just as successful is low. From this particular example, it can then be surmised that a successful logo has to make sense in relation to what it is representing.  This may or may not be the case in terms of all logos, considering the Carl's Jr. logo is a five pointed star, but it is definitely something to keep in mind.  As for the LV logotype, the message is clear, it is simple, and elegantly design... much like its many products... wouldn't you agree?
