Vintage/antique silver cigarette case.  Hallmarked ‘800’ silver with a raised gold crest on its front.  Crest appears to be either a hedgehog or a crested porcupine with a Crown above its back.  I wasn’t successful finding a crowned hedgehog in any heraldry reference but the hedgehog seems to mean “thoughtful provider” and and ancient heraldic symbol of “cunning and perseverance”.  

It has both elastic cigarette ‘keepers’ still intact and it’s period engraved saying:  “Berlin1915" with the initials “F.M.H.”  The case’s catch/closure is fully functional and secure.  Thanks for looking!
