I hope this is allowed since I'm not the one selling it... please delete if not. I wanted to post it more for photo reference.
There's an original production Colonial Warrior Cape up for auction tomorrow (sorry I posted probably too late for anyone to sign up and participate if desired... I should have looked at the auction listing sooner than I did). Link is at www.icollector.com/Battlestar-Galactica-1978-TV-Colonial-Warrior-Cape-VI734_i35533521 . For what it's worth, I've bought from this auctioneer before and personally I trust that their items are authentic. It's neat seeing that there's still an original BSG costume piece still floating around out there.
