Not Batman
Parents might not be able to distinguish between all the different superheros, but for children, there’s a crucial different between Batman, Superman, Spiderman and all the other heroes. A kid might be obsessed with Superman, and hate Batman, or the other way around. Children and DC fans around the world would be very upset with this backpack.
Either way, even if you’re not a fan of Marvel or DC, we’re all familiar on those superheros in one way or another, and most of us grew up on them. Whoever is responsible for this mistake is clearly not a fan of the genre, but worse than that, it almost seems as if he doesn’t even live on this planet. I mean, come on, it’s clear that Batman must have something to do with a bat symbol.
