It's transcription reads:
Esther, Why haven't you answer my last letter? You treated me real bad. Say, aren't you coming to see us soon. You and Rubin just ride by and never ________ Hope he is well _____. Tell Mrs. R___ she must come sometimes. Are you most married. What are you going to do Easter? Come up here please do. Answer soon. Nannie Lee
The sender of this card was Nannie Lee with no surname given. I suspect this may have been Esther's cousin Nannie Lee Elliott, though I cannot be completely sure. The Rubin who is mentioned would have been Esther's younger brother. Mrs. R___ was Esther's mother Hattie Richardson.
Notice the mention of being married? Esther was married the following November to Boss Henry Talbott.
