I have a brick from the Mapes site that is "new and unused," truly a BS70. I even put down plastic before I laid it on the ground at 1st and Virginia, so it wouldn't get any dirt on it. Then I picked it up, wrapped it in cellophane, and brought it home. So you know I'm not lying when I say it's "from the Mapes site."

You suppose it's worth more than this beat up old hunk of clay? If so, I have access to a VERY large quantity!
