Being a British expat, I would love to collect and display Blitz / British home front items.  However in all practicality the WW1 and WW2 US Home Front is more available and is less documented / researched than the GI experience at the front on Land, Sea and Air.  In both World Wars the National pride and duty so save, make do and support the war effort with Liberty Loans and War Bonds.  Within this subject there is also the "sweetheart" material originated at home and abroad.
