https://jan-hamernik.com/replicas/mar...
Marauder's Map v7 is a series of replicas (this is just one of them), each designed to match the film it appeared in, or including my very own custom designs and ideas.
There's over a decade of extensive research behind the replicas, for more (much more) information visit the link above.
