So groovy, that’s ingenious for Batman lovers ( pun intended ) and I’m bias about the name, something about it. This is the Underoos wearing Batman I grew up with and had toys of that I believe are in a dusty box somewhere. Unfortunately I played with my toys like a chimpanzee hence why probably no collectible value is left whatsoever, just irreplaceable childhood memories. Which in wisdom is the real fortune I guess. Only thing better is to watch your own kids play and bringing us full circle because Valentine’s day is the number one day for conception.
