The description states:
SQUEEZING JUICE FROM SORGHUM GRASS
This juice is boiled in an evaporator until it becomes Heavy SORGUM SYRUP.
–This sorghum syrup is distinct from molasses, which is made from cane or beet sugar. More recently, sorghum is being used for the production of ethanol biofuel.
This card likely dates from the 1950s.
