Blood Thirsty 'Hannibal' Fans Want Props ... From Huge Show Auction

"Hannibal" fans are proving their thirst is real for anything connected to the show.

Fans of the show -- or "Fannibals" -- flocked to an auction site to bid on props from the show, which NBC canceled last year, and the mad rush caused actually crashed the site.

Ryan Albertson, the auction manager at Prop Store, tells us fans are bidding on some gnarly stuff ... like the creepy Wendigo bust (pictured above) -- and also the gown Bedelia Du Maurier (Gillian Anderson) wore in the the series finale.

There's plenty to choose from with more than 1,200 items up for bid. Where else ya gonna find a fake dead cat in a burial box ... complete with fake maggots?

Yeah, they got that.
