Dracula Horror Series, mined one of that decade's many pseudoscientific obsessions. Horrorscope apparently only lasted four titles (looks like a fifth was published in Germany only); don't know what happened to the other eight signs of the zodiac! One can only imagine the rest of the series...
I couldn't find cover artist info but I think it's a safe guess to posit John Holmes, a British artist whose bizarre illustrations adorned H.P. Lovecraft Ballantine paperbacks around the same time.
