Muy bonitos estos logos con diseño monograma, por si no saben el significado de esta palabra aquí les dejo lo que dice la Wikipedia, en ingles y español.
Español:
Monograma es un símbolo formado generalmente por cifras y letras entrelazadas en conjunto, que como abreviatura se emplea en sellos, marcas, monedas, logotipos de empresas, etc.
Ingles:
A monogram is a motif made by overlapping or combining two or more letters or other graphemes to form one symbol. Monograms are often made by combining the initials of an individual or a company, and may be used as recognizable symbols or logos. A series of uncombined initials, such as “TCM”, is properly referred to as a cypher and is not, strictly speaking, a monogram, although ciphers are frequently referred to as monograms.
