Shakur in Graffiti

Hello Steemians!!
Good day to you all.
I saw these nice art piece (graffiti) inside Kwame Nkrumah University of Science and Technology (KNUST) campus at their Art faculty which I find it interesting. Theses works were made by an artist named Mr. Daniel Mensah also known as Skyscraper. He wasn't around to explain the concept behind his work to me so let's deal with the aesthetic qualities now fellow Steemians.

Thanks for checking it out.
