OMG, doing a Sunday afternoon browsing around Etsy and come across these amazing pendants. They use a picture of taken from a comic book and you can choose whether to have them as a necklace or a keyring.
As the pictures are cut from comics books no two would be same, so you would end up with a unique piece.
Lots to choose from, having a hard time deciding what to chose from myself, mainly Marvel with a few DC thrown in.
Whole collection can be found here https://www.etsy.com/uk/shop/GeekyLime
