I have watched the Florida flick
The Brides Wore Blood dozens of times. I can't begin to tell you why. It's cheap, it's dull, it barely makes any sense. But I keep ... coming ... back. That's one of the reasons I interviewed producer/effects artist/actor Tom Rahner for my upcoming book, and why I was so excited when none other than Fred Olen Ray sent me a quick scan of this newspaper ad for the film's preview screening at the Fernandina Beach Municipal Auditorium and Recreation Center in June 1972.
Unfortunately, the scan is too fuzzy for us to read the accompanying article, but I like the nice big advertisement. The only other screening for this film that we know of was a Midnight show at the University of South Florida in May 1975 as part of the "Head Theater" program.
Fred also claims he used to have some stills from the film, but I've yet to see them. I've pasted the DVD cover below, along with the Goodtimes label VHS cover (I first saw the film via this release, which was available at Kmart for a mere $3 back in the late 1980s), and a few quick screen grabs for your edification.
