Fine work as usual from Christian Annyas: a look at the design of the Warner Bros logo from 1923 to the present. The classic "WB" shield of my Bugs-and-Daffy-saturated youth will always be a favorite, but I do like the Saul Bass logo of the 70s and early 80s:
Affleck's Argo and Soderbergh's Magic Mike both used the Bass logo in place of the contemporary logo, which is the kind of little detail I love.
Here's a collection of video and stills from most of the movie title sequences created by Saul Bass.
"PROJECTIONISTS - PULL CURTAIN BEFORE TITLES".
This is the text of a note that was stuck on the cans when the reels of film for "The Man With the Golden Arm" arrived at US movie theatres in 1955. Until then the credits were referred to as 'popcorn time.' Audiences resented them and projectionists only pulled back the curtains to reveal the screen once they'd finished. Saul Bass' powerful title sequence for "The Man With the Golden Arm" changed the way directors and designers would treat the opening titles.
