A patent print poster of a Safety or Restraining Device invented by Mabel E. McCalmont. The patent was issued by the United States Patent Office on May 7, 1907. It is easy to imagine a similar device in a turn of the century insane asylum. This one definitely qualifies as bizarre.
Patent prints allow you to have a piece of history in your home, office, man cave, geek den or anywhere you wish to add an interesting touch.
