Mego Comic Action Heroes Batmobile Commercial

Here's a Mego commercial from 1976 of the Batman related Comic Action Heroes Batmobile set. I had this set when I was a kid. I thought it was cool, but my activator never really worked. The spring was so stiff you could never get to stay locked down so you could pull the plunger and cause it to blow up the bridge. It only worked a couple of times for me so the fun didn't last long. I think my dad threw away the set (among tons of other collectibles). Wish I still had today. Need to try and pick one up off a eBay one day. The commercial says Robin is sold separately, but mine came with not only Batman, but Robin, The Joker, and The Penguin.
