Accor Hotels 50th Anniversary Logo
Accor Hotels normally uses a bird silhouette the form the left diagonal and cross of the letter A. The designers of their anniversary mark cleverly took that same shape and placed at the top of a number five to form the year the company is celebrating. Combined with a classy serifed font tucking just below their name, this logo is a really sharp design and one that was combined with other colors and elements in their marketing.
