This amazing vintage Rap Tees shirt is from the original Political Rap album, By All Means Necessary which was released by the hip hop group Boogie Down Productions on May 31st 1988. The album featured the singles "Stop the Violence" and "My Philosophy". This shirt appears to be a hand made shirt from one of the group's two dates in Philadelphia in 1988 at the famous Spectrum area which used to reside in South Philly.
Their June 25th 1988 date featured artists Doug E Fresh, Kool Mo Dee, Biz Markie, Ice-T, and Eric B and Rakim. They then played again later in the year on September 4th 1988 with appearances by Public Enemy, Eric B and Rakim, Kool Mo Dee, Big Daddy Kane, Biz Markie and Stetsasonic.
The back of this shirt features the BDP design of KRS-1 re-enacting the famous photo of Malcom X peering out the window while holding a carbine rifle. This graphic appears to be hand drawn, possibly traced from the record album cover.
