Title: Mega Rock Poster
Notes: Published in the UK.
"Mega Rock Poster" magazine came with 2x "pocket mag" supplement magazines titled "Beastie Mania" (no, we did not steal the name!) and Run-DMC Special.
These were originally sealed together.You can see on the MRP magazine the incomplete spelling of "OYS" which was completed with "BEASTIE B" once the pocket mag was layed on top of it.
