The DC Batman Fronted Lego Heroes Kids Athletic T-Shirt is a 90% cotton/10% polyester athletic style shirt. These LEGO Batman men are all mixed up on this shirt! Personally I don't think any of these men would appreciate you swapping their heads out like that?! I mean can you imagine Batman waking up with a Joker face? I don't think he would be pleased, smiling doesn't seem to be the Batman's thing. But that is the risk you take when you decide to be a LEGO man. The DC Batman Fronted Lego Heroes Kids Athletic T-Shirt certainly pulled the ol' switch - a - roo on us but I still think LEGOs are pretty cool even if Two-Face is rockin' Bane's bare chest.
