Ballantine Cover Font?

Hi Folks,

Here's an obscure trivia question I haven't been able to track down on the web:

Does anyone know the font used for the distinctive covers of the 1973 Ballantine paperbacks? Is there a Mac version, or a close approximation available?

This will help us do lettering for signs on our model railroad -- The Grey Havens, Lorien & Gondor

Thanks,
Maureen
