No facts here,  but I would guess the black might have had the smaller run, The FU were selling the clear at gigs for at least two years, and I kept finding clear copy's at shops until well after SOIP came out. In fact I know a shop that still has one copy of the clear. I just checked and I have four clear and no black copy, and I gave away three or four clear before I gave up the search for the golden ticket. now I have to find the black copy, rats! well at least I have clear blue Daredevil, even if it is a bootleg.....
