For Jake (and any others):  Greenwood and Associates excavated a site  with 
several early- to mid-century restaurants and lunch counters, yielding an  
abundance of the typical ceramics.  One unique type is a compartmented  plate with 
"dimples,"  two small round depressions on the brim, as if to  hold 
condiments.  These have not been reported elsewhere.
