Based on the Supreme Court's ruling in Scott v. Sandford, the Missouri Compromise was found to be unconstitutional.

Explanation:

Dred Scott v. Sandford was a judicial claim, crucial in the history of the United States, resolved by the Supreme Court in 1857, in which it was decided to deprive any inhabitant of African descent, whether they were slaves or not, the right to citizenship and the authority to prohibit slavery in federal territories of the country was removed from Congress. The decision was drafted by Chief Justice Roger B. Taney. The fury that caused this ruling among the abolitionists was an important factor in the explosion of the Civil War.

The court ruled that African-Americans had no right to freedom or citizenship. As they were not citizens, they did not have the legal capacity to file a lawsuit in federal court. As slaves were private property, Congress did not have the power to regulate slavery in the territories and could not revoke the rights of a slave owner according to the place where he lived. This decision nullified the essence of the Missouri Compromise, which divided the territories into free or slave jurisdictions. Speaking on behalf of the majority, Taney ruled that as Scott simply considered himself the private property of his owners, he was subject to the Fifth Amendment to the United States Constitution, which prohibits taking ownership of his owner "without due process".

the iconic cartoon that you are talking about is probably a man standing on top of a country with his legs spread wide. 

this cartoon suggests that europeans are powerful enough to subdue an entire continent. this was a satirical image that was drawn during the time of the colonization of the british empire in africa.

this image was inspired by the plans of the british empire to create telegraph lines all over africa promoting the further spread of its colonies through faster communication. the picture depicts the colonial mentality of the british empire in general as well as the struggle of africans to claim their own land. hope this !
