I found this USCT recruiting poster interesting. Note the use of images: 1. USCT taking the chains off slaves. 2. Former slaves reading and going to school. 3. The Union officer standing on a Confederate flag while a enslave rips the flag. 4. The slogan "Freedom to the Slaves". 5. The slave cap on the top of the US flag. 6. The number of stars on the US flag shows the Confederate States ever left. 7. The Union officer looking towards heaven for guidance or praise. This USCT recruiting poster shows what was felt would be effective in getting blacks to join the Union Army. I wonder how effective this poster was in getting black to join the Union Army?
