I found cards similar to this, except Dora the Explorer, and StarW Wars etc, in downtown Vancouver. I didn't buy a deck but, if they're made from Bicycle then they should be trust worthy. I would recommend checking out a Chinatown, not to be racist, if you have on near you because that's where I was when I found the Dora and Star Wars ones, they may have Harry Potter.
