The 100 percent polyester Batman Symbol Two-Tone Kids T-Shirt is a perfect shirt for little fans of the famous Caped Crusader. I don't think the Dark Knight has stopped being popular since the era of Adam West! I know I grew up on that and the good ol' Michael Keaton movies. I believe that's where the symbol is from on the Batman Symbol Two-Tone Kids T-Shirt! Not only that, but there are comic frames on the side...pretty sweet.
