Cool Batmobile from the 70s

After the Kohner Push Puppet which sells for around $1000/US this is my holy grail of Batman collectibles.  It came in red, blue and I think Black but I like the red and the blue best of all.
Back in the 70s people weren't so keen on getting the details just right-- so this car was perfectly fine for your average kid, who got it-- its the Batmobile, even though it's read and Batman painted his name on the hood-- unlike how we saw it on the show.

Cool piece but I'm a sucker for gaudy colors like these.
