Answer:
First we need to understand a little Backround for this question, Minority groups such as african americans were realeased from slavery but didn't have the same access to education as White Americans. The 15th amendment Targeted these minorities because they weren't being educated because of the color of their skin but needed to be educated to pass a Literacy test and be able to vote.
The injustice was that 5 young black men were charged and arrested for a crime that they did not commit, even with the fact that there was virtually no concrete evidence that pointed to them.
To restrict the ability of African Americans to exercise voting rights.
The black community had less access to education than whites even after slavery was ended; thus their literacy rates were lower. They also experienced much poverty because of prejudice against them in the economic system of the country, so poll taxes could keep them from going to the polls to vote. The "grandfather clauses" were exemptions granted by some states to those whose forefathers ("grandfathers") had full voting rights prior to the Civil War, so if there were poor or illiterate whites, they could vote freely while blacks (whose ancestors had been slaves) were subjected to the laws restricting their voting ability.
These sorts of restrictions against black voters prompted much of the activism of the civil rights movement that began in the middle of the 20th century.
Not really decorated in that sense as making them look "good" i guess, but they were mostly leather bound and covered in tar to help preserve the wood.
Hope this Helps!
