Actually, the middle title, from the trailer on the US DVD release, is not the original font. The Warners people apparently found the original textless version of the 1958 trailer but could not find the text elements to superimpose onto it, so they cooked up look-alikes. Note that it says "Released by Warner Bros."-- it was actually released by Universal International, and did not become a Warner property until Seven Arts (which bought the rights from Hammer in the 60s) merged with Warners about 1967.
Hi there Ted - You learn something new every day, thanks for the information regarding the US trailer. The story behind the title cards for DRACULA (and its trailer it would seem) would make an interesting article in itself.
