The poster created in 1944 during the 2nd World War by the US Navy Ministry of Supply and signed by Hotchkiss Usnr, shows a couple of parents intent on writing a letter to his own son, who, as it suggests the picture exposed on the table, is a sailor.
The boy’s father says to his wife the text of the letter: “Tell him that the people here hope that the boys are appreciating all the good food that we grow for them” concluding the phrase warning him against food wastage: “P.S: Also tell him I will punish him is if he wasted.”
