This "Carte Postale" shows no signs of ever having been stamped or mailed, but is intriguing because of the address:
Private Samuel Spriggs
Battery C G S(?) 1st field Artillers
American Expeditionary Forces
France

I can't quite make out what the guy is saying about the french girls... "Here is - - - one of the French girls - - - my name".
Any suggestions?
