Barry O'Riordan

Credited for jacket logo design in 1979. NB. currently unclear who this might be. There is an Irish painter of that name, though his interest in "old traditional style signwriting" didn't occur until the 1990s. IMDb also lists a producer / director / graphic designer of this name who worked with Kevin Brownlow, however there is also a chance this site maybe mixing up two people of the same name.
