A Paw Print on the Wall
It’s impawsible for a pet to have left their paw print on this brick after it was laid on the wall. So it’s more likely that the brick came like this from the brick factory, because once bricks are baked, the force required to mark them would have to be significant. But if these are old bricks, they might have been dried in fields where a coyote ran across them and left their print.
