I really like this clever gaming passport design by htCRU. It’s main purpose is to be a t-shirt, not fit in your pocket, and you can buy it at the link there.
There’s quite a lot of detail put into this, far more than you’d imagine for a singular figure. There are dozens of gaming references to be found, and some that even I can’t identify. If you someone wants to come up with a comprehensive list, I’ll be most impressed.
