So one of the bits of merch we're considering is a set of hero and villain ID cards for the main characters. The Blue and Red cards, if you will. There are two basic forms that this could take.
The first would be a printed, laminated card. Pros: Would more accurately portray the wallet cards that we have seen in the comic. Easier to make in small quantities. Cons: A laminated card doesn't look the same as an actual printed plastic card. Not much you can do with it besides stick it in your wallet.
The second possibility would be a printed card slipped into a plastic badge holder on some kind of cord or lanyard. Pros: Allows for a slightly larger card (more info and artwork.) Could be worn or clipped to a bag. Cons: Not exactly what was shown in the comic. Have to source the holders and the lanyards.
