This RARE marmalade jar is in very nice estate condition. It is incised on the bottom Fiesta HLCo. USA. 

Vintage Fiesta marmalade jars were in production from mid 1936 with red being discontinued in early 1943. The bodies would have been slip cast holloware with the seams smoothed by hand.  Marmalades will be marked in the mold. It is speculated that they were either speciality items or not big sellers since they appear to be quite SCARCE.  circa 1936 - 1943
