This fun and retro Car & Camper salt and pepper shaker set (they hook together at the hitch) has been in my personal S&P collection since the 1990s.  The car and camper both measure 3" in length (6" when hitched).  They are mint with no chips, cracks or "crazing" (a network of fine cracks in the surface of glazed ceramic) and include plastic stoppers.  They were never used as shakers; only displayed on a collector's shelf.  Sorry no original box.
