Know your Vegvisirs. I was drawing these, wondered why the different versions around the place. Nobody can figure out what Björks tattoo actually is, a Galdrabók one roughly done most likely vegvisir symbol
the valknut- vikings painted this on their shields to call the Valkyrie to take them to Valhalla if they were killed, Jake had this tattooed on his forearm in honor if his viking decent/roots. Along with some ancient runes.
