I found these on the Portal to Texas History page. One is a Mealy photo and the other is a Harper photo.
This first one is the Harper photo of a middle-aged African American man.
The second is the Mealy photo of two young African American boys in knee britches.
I wonder who they are? Are they famous in our history? It is so frustrating! Please label your photos, otherwise, you too may be the subject of an unknown photo!
