History Today

Ok. Lets say you were told you could go back in time for 12 hours, and have nothing you did change history (or the future) at all, and you were told you could do five specific things, and bring back five non-living things (nothing HUGE like a castle or ship, car sized at the most, and as small as you want), what would each of these things be?
You are not allowed to sell any of the things you take back, and you may not take a camera with you back in time.

You don't have any powers to jump from place to place, they don't know you are comming so can't save anything that was made in another place 100 years earlier for your visit. People will help you with doing those five things and give you those five things though.
Be fair when picking things with what is 'one'.  You can bring back one ring or one coin, but not a box of jewlery or a bag of coins. You can look at how one craftsman makes cups, cut can't look at all the craftsmen as one thing, you can go to on castly, but you can say visit all the castles as one thing etc.  

I'll have to have a think about this myself! but once I've thought I'll post my answers as a reply, and I invite you all to do the same!
