Amerarcana
A future word describing indecipherable objects: mysterious red-white-and-blue cloth, tattered paperback copies of the Constitution, Barbie dolls, portraits of Thomas Jefferson, carved Philadelphia chairs, dog licenses, coins, photos of things called World Trade Center and Golden Gate Bridge. They will be rumored to have come from a lost civilization, but one few people can believe ever existed.
'Another piece of Amerarcana?' he wondered, as he brushed the mud off the strange, almost perfectly round object, circled by small red lines and weird black marks which were shaped like 'M-a-j-o-r -L-e-a-g-u-e' and might once have meant something, although no one could say.
