From November 1959 this is Duke 314, “I’ll Take Care of You” backed with “That’s Why” by Bobby Bland. Note that the song was written by Brook Benton. It made #2 on Billboard’s R&B chart in early 1960.
The next Duke release by Bland was “Lead Me On”, issued in March 1960. I haven’t been able to confirm that one on 78 yet.
