Greatest Show on Earth

Unknown maker used unusual technique to cut puzzle into sections first, interlocking the border sections with large multiple piece knobs.  Unfortunately, the pieces within sections do not fully interlock, so the sections don't fully interlock.  Maker also copied Pastime figure pieces but we don't think puzzle was cut by a Parker Brothers Pastime cutter.  Still, a very interesting well cut puzzle with 41 figure pieces and semi-color line cutting.  Artist also unknown.
