@LastSon0fMars Yeah, they’re just a piece of thin cardboard with a string from one end to the other to hold them on. Nothing fancy, but fun, all the same.
I have Batman Day and DC You masks that are similar (minus the string on the back). I never wore them, but instead stuck them in one of my DC art wall collages, which is where the masks I have from these bundles so far now reside.
Catwoman had the Justice League Last Ride, Batman: Reptillan and Batman/Fortnite #1 and #3. There were two packs with Catwoman mask and I was a little more interested in the Last Ride book than the Future State Red Hood one.
Joker had Robin, and then Batman/Fortnite #1, 3 and 5. It was the only remaining Animated Joker.
Based on the eBay listing that pic is from, the DCAU Joker mask comes with that set too (and as said earlier in the thread, I’m thinking the mask placement is mostly random), which looks to be relatively free of Batman/Fortnite duplication.
