This weekend I visited the magical Mercer Museum which has exhibits on over 60 early American trades like candy making, woodworking, blacksmithing, shaving, coopering (that would be making barrels, as I learned). There's also a replica of a general store and post office. I came upon this poster drafted by the museum's founder, Henry Mercer.  which I haven't been able to stop thinking about. Do you think it is possible to reorganize the primary secondary tools to reflect today's world? Or does some of this still hold?
