Seriously, to put it very simply, we're still working at 1970 wages. Some of it appears to be by hand, other sections look like they're computer-generated. I'll also use a gray shade, which I'll do on the computer. I find one. I work everyday because of the incessant nature of deadlines in syndicated work.
Some days are better than others, but there's always something stupid going on to comment on.
Like any piece of art, every one takes it's own time. I put a lot of emphasis on the artwork, so it probably tends to take longer than the average comic. We don't time it while we're doing it, we just lose ourselves in the work. So it's a lead time of several weeks. All of the above and none of the above.
