It looks like he wears briefs! Ha ha! Here's a photo I saw over at my favorite 1966 Batman Message Board. It was posted by my buddy Darren & he explained that this is a brand-new product (for Men) that they're selling at Wal-Mart. He said they were only about 7 or 8 bucks, not a bad price! I might have to get a pair. You know, for the ladies. MEOW!!
This Vintage TV Commercial will bring back fond memories to anybody who is over the age of 30! It's for a famous product called UNDEROOS which were basically little kid's underwear made to look like superhero costumes. I know that I personally had the ones of Superman, Batman, & The Flash, ha ha! My sister had the Wonder Woman set & practically lived in them, ha ha!
