So who designed flyers from the hardcore/rave days?

Fantazia had their own in house designer back in 1992 who did many of their classic flyers, Obsession similarly used some one they new and who was local to their home town of Cheltenham. Many of the other rave companies like Helterskelter, World Dance, Dreamscape, Raindance and more used either Junior Tomlin or Pez. If you click their names you can read interviews and profiles on both of them. Well worth checking out for a bit of scene history.
