Made from 100% Cotton, this white t-shirt features a classic, purposely distressed image of Thor, god of thunder, holding aloft his mighty Uru hammer, Mjolnir, and decreeing this time as... the Time of the Hammer!  Ok, nothing that fancy.  It's a play on words, dummy!  Anyway, Thor likes to throw his hammer at the sun when it's just too dang bright.  Some parts of the world go without daylight when Thor gets grouchy!
