The 1991 Pro Set Yo! MTV Raps The Beastie Boys #103 is a vintage music trading card manufactured by Pro Set under its MusiCards brand, serving as the companion update piece to their earlier number #102 entry in the checklist. Capturing the hip-hop pioneers in an iconic close-up portrait, the card shows MCA (Adam Yauch) peering forward next to a sunglass-and-fedora clad Mike D (Michael Diamond), while Ad-Rock (Adam Horovitz) cheekily poses sideways at the bottom of the frame.
