Copper Rubbings

My friend (who has more toys than I do) gave me a piece of copper foil and a little tool package. I was showing Timothy how to make an image on the copper by rubbing it with something under the copper. He came up with the plan to use coins and this is the result. After getting the impression I brushed black India Ink over the copper and polished it after the ink dried. I did seal with a coat of Mod Podge.
