The soldier serving overseas and far from home was annoyed and upset when his girl wrote breaking off their engagement and asking for her photograph back.
A creative fellow, he went out and collected from his buddies all the unwanted photographs of women that he could find, bundled them all together and sent them to her with a note stating the following:
"Dear Mary, I can not remember which one is you ... please keep YOUR photo and return the others!" ---------------------------------------------- |
